A resistor converts 350 J of electrical energy to other forms of energy. What is the amount of charge that flows through it when a potential difference of 7 V is applied across it?

50C

Explanation:

Given parameters:

Electrical energy  = 350J

Potential difference  = 7V

Unknown:

Amount of charge = ?

Solution:

To solve this problem, use the expression below;

  E  = q x v

E is the electrical energy

q is the quantity of charge

v is the voltage

Insert the parameters and solve for q;

            350 = q x 7

            q =

             q = 50C
