Voltage and Current | Basic Concepts Of Electricity
With the circuit''s continuity broken between points 2 and 3, the polarity of the voltage dropped between points 2 and 3 is "+" for point 2 and "-" for point 3. The battery''s polarity (1 "+" and 4 "-") is trying to push the current through the loop clockwise from 1 to 2 to 3 to 4 and back to 1 again.

$begingroup$ @Ghost The current is greater before the resistor is added to the circuit. But the resistor does not induce spatial variations in current after it has been added. There is no way the current can vary spatially (be different at different locations) if you require a steady state (no buildup of charge) together with charge conservation.
Path of an electron through an electric circuit
In fact, the path for electric current is through the battery, through the electrolyte, then back out again. For every bit of charge that flows out of one battery terminal, equal charge must always flow through the battery, and equal charge must also flow into the other terminal. A battery is a good conductor; a short circuit.
19.3 Parallel Circuits
Although 0.62 A flows through the entire circuit, note that this current does not flow through each resistor. However, because electric charge must be conserved in a circuit, the sum of the currents going through each branch of the circuit must add up to the current going through the battery.
Physics Tutorial: Series Circuits
In a series circuit, each device is connected in a manner such that there is only one pathway by which charge can traverse the external circuit. Each charge passing through the loop of the external circuit will pass through each resistor in consecutive fashion. This Lesson focuses on how this type of connection affects the relationship between resistance, current, and voltage …

How does current flow through a voltage source?
Since the circuit elements are in series, the current through each element is identical. An ideal voltage source will support any current through an external circuit.

How to Calculate Voltage Across a Resistor (with Pictures)
Think about how the current flows. In a parallel circuit, the current flows across each path available to it. Current will flow through the wire on the left, cross the left resistor, and reach the other end. At the same time, current will flow through the wire on the right, cross the right resistor, and reach the end.
What is the current before arriving a resistor and after leaving it in ...
This congestion also slows down the current before entering the resistor and lessen the overall electrons flow through the wire because the resistor is limiting the total amount of electrons that can pass the resistor. So even if the wire can carry more electrons, but the resistor is limiting it, the wire only supplies the amount of electrons ...

Why is the current entering a conductor the same as the one …
Secondly. let''s make the assumption that the current does in fact decrease as it passes through a resistor. This is going to be the assumption we are going to contradict. Saying that a current decreases after passing due to resistance is sort of like saying that the flow of water passing through a pipe decreases due to friction.
19.2: Electric Current
The electrical driving force across the terminals of a cell is known as the terminal voltage (difference) and is measured in volts. When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf.

Will current pass without any resistance?
There is no current flowing from its positive to its negative end because both the air and the internal insulation of the battery are preventing current flow. Back to your example. Let''s say you have an wire connected to a positive and negative end of a battery. The current will flow through the wire to the negative end of the battery.
electric circuits
Since the voltage has dropped to zero, no current will pass through the resistor. To put this another way, perhaps more clearly, there is no arbitrary rule that says a shorted resistor cannot have current pass through it, but the voltage across a resistor is proportional to the current, and the voltage across a short circuit is defined to be zero.
When current flows from a battery, does voltage decrease?
I understand voltage to be a potential for electrons to be pushed through a circuit. However, in a battery, you have an electron build-up that creates the voltage. Once current begins to flow, electrons are now moving through the circuit. Does this mean that the voltage actually begins to decrease as a direct result of current flow?

Alright, this can actually be pretty easily explained without too many equations and only a single thing to keep in mind: charge cannot pile up inside a metal. In other words, electrons won''t ever pile up within a wire. If they did, even for a tiny amount of time, then they''d repel each other super strongly due to the $1/r^2$ dependence of the electric force electrons exert on one another ...

Why does DC current pass initially through a capacitor while it is ...
Is true that electrons don''t go through the insulator of the capacitor, so there is no ''current flowing'' in the sense of electrons passing from one side to the other. But, as the charges in one plate of the cap have influence on the charges on the other side (attracting or pushing) there is some kind of ''current'' going through.Maxwell called it ''displacement current''.
Why doesn''t current decrease when it passes through a resistor?
So consequently charge entering the battery decreases, Therefore current decreases in the entire circuit. So basically this explains the statement " resistor not only has an effect on the current passing through it but also the currents passing through entire circuit to which it is connected". P.S. So statement in my question is disproved.

Why don''t electrons just "pile up" on the positive side of a battery?

Batteries, current, and Ohm''s law
A copper wire has a length of 160 m and a diameter of 1.00 mm. If the wire is connected to a 1.5-volt battery, how much current flows through the wire? The current can be found from Ohm''s Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated.
Does current flow back to the source through earth?
A more modern and safer way to achieve this protection is earth leakage protection - a system that detects, through the Ampère-law-begotten "magneto motive force MMF)", when the current through the active is different from that through the neutral. In this system, both active and neutral lines pass through a torus-shapen ferromanetic core.
Why does voltage drop to zero?
Why voltage drops to zero after passing through a single resistance circuit. Because one terminal of the resistance is connected to the battery''s zero potential or ground. Do charges slow down when passing through resistance and if they do then why isn''t it effecting current? Current depends on the no. of carriers passing through a cross-section.
Is the current lower after a resistor?
If you now add a resistor in series into this circuit – the current of the circuit will be smaller than it was. So yes, the resistor does reduce the current. (But the current flowing into the resistor is still the same as the current flowing out.) This is one of the mindset shifts a beginner has to go through when learning electronics.

The inability to let go or release from an electric charge is more likely to occur with an alternating current than a direct current because an alternating current inhibits the let go response at a lower current. Direct current (DC), invented by Thomas Edison, is an electrical current that only flows in one direction.
