Question

A current of 0.2A flows through a component with a resistance of 40ohms calculate the potential difference

Answer 1

Answer:

8V

Explanation:

Given parameters:

Current = 0.2A

Resistance  = 40ohms

Unknown:

Potential difference = ?

Solution:

Potential difference is force that drives current in an electric circuit.

According to Ohms law, it is given as;

   V = IR

V is the potential difference

I is the current

R is the resistance

 Now, insert the parameters and solve;

    V = 0.2 x 40  = 8V
