Answer:
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
