Question

Calculate the current in a circuit whose electromotive force is 100 volts and resistance is 5 Ohms. Use the formula i = e/r.

Answer 1

Answer:
I = 20 amperes

Explanation:
The relation between current, voltage and resistance can be expressed using Ohm's law as follows:
V = I*R
where:
V is the volt = 100 volts
I is the current we want to calculate
R is the resistance = 5 Ohm

Substitute with the givens in the above relation to get the current as follows:
V = I*R
I = v/r
I = 100/5
I = 20 amperes

Hope this helps :)

Answer 2

I=20 amps.
By the way, did you know that this is Ohm's Law?
