Question

In a closed circuit containing one resistor and a battery, if the voltage in the battery increases, the current going through the resistor increases. Why does this occur?

Answer 1

V= IR is Ohm's Law.

V is voltage in volts
I is current in amps
R is resistance in ohm's

So, if we're trying to solve for I, aka current, then we should rearrange the equation.

V=IR
V/R = I

So, if you divide a larger number (Volts) by the same number (Ohm's), then you must get a larger number.

Ex.
The voltage in the circuit is 20V, the resistance is 5 Ohms.
V/R = I
20/5 =I
4 =I

But now if we increase voltage to 40 and keep resistance the same, we will prove that the current is higher!

V/R =I
40/5= I
8 = I

Therefore, we just proved that the current going through the same resistor will increase, as when we increased our voltage from ,20V to 40V, we got an increased current as well. Hope this helps you!! ((:

Answer 2

as the electrons are pushed more by the battery, they move faster through the circuit
