Question

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

Answer 1

Energy supplied to the charge is given by

`U = q\Delta V`

here we know that

`q = 1C`

also we have

`\Delta V = 12 volts`

now we have

`U = (1)(12) J`

`U = 12 J`

so the energy given by battery will be 12 J
