Question

What is the potential difference if the current is 2A and the resistance is 0.5Ω?

Answer 1

1A

Step-by-step explanation:

Given parameters:

Current = 2A

Resistance = 0.5Ω

Unknown:

Potential difference = ?

Solution:

To solve this problem, we use ohm's law which expressed below:

V = IR

V is the potential difference

I is the current

R is the resistance

Now insert the parameters and solve;

V = 2 x 0.5 = 1A
