Abattery is rated at 12 v and 160 a-h. how much energy does the battery store? what is the cost of this energy at $0. 15/kwh?

The cost of energy is 0.29$.

Explanation:

Given that,

Voltage V= 12 V

Charge Q= 160 A-h

We need to calculate the energy

Using formula of energy

Where, E = energy

I= current

V = Potential

t = time

Put the value into the formula

The cost of this energy at 0.15/kwh

Here, Energy = power x time

In units,

But ,  Energy in 1 hour is:

So, The cost of this energy is

Hence, The cost of energy is 0.29$.
