Explanation:
we know that
charge = q = 3 coulombs
potential difference = 125 - 115 =10v
Energy =?
FORMULA: POTENTIAL DIFFERENCE = WORK DONE ÷ CHARGE
V = W ÷ Q
10 = W ÷ 3
W = 3 × 10
W = 30JOULES
Therefore, The work done in moving a charge of 3 coulomb from a point at volts 115 to a point at 125 volts is 30 JOULES
