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

1A

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
