Answer:
1807056 J
Explanation:
Energy: This can be defined as the ability or the capacity to do work. The S.I unit of energy is Joules(J).
The expression for electric energy is given as,
Using,
E = VIt...................... Equation 1
Where E = Electric Energy, V = Voltage, I = current, t = time.
Given: V = 12 V, I = 8.9 A, t = 4.7 hours = 4.7×3600 = 16920 s
Substitute into equation 1
E = 12(8.9)(16920)
E = 1807056 J.
Hence the amount of energy delivered to the battery = 1807056 J
