Answer:600 JExplanation:Energy: This can be defined as the ability or the capacity to perform work. The S.I unit of energy is Joules.

From the question,

The formula of Electrical Energy is given as,

E = VIt……………………… Equation 1

Where E = Electrical Energy, V = Voltage, I = current, t = time

or,

E = VI’………………….. Equation 2

Where I’ = rating of the battery in Ampere-hours

Given: V = 12 V, I’ = 50 A-hour

E = 12(50)

E = 600 JHence the energy stored in the battery = 600 JAnswer:E = 600 J

Explanation:The power is

P = W / t = E / t

E = P t

The electrical power is

P = V I

We substitute

E = V I t

Let’s calculate

E = 12 50 1

E = 600 J

This is the energy stored in the battery
