Question

6 volt battery produces a current of 0.5 amps. What is power in the circuit?

Answer 1

`P=3W`

Explanation:

Given values for potential difference (voltage) and current, we can calculate the power of the circuit using the following equation:

`P=VI`

We have `V=6V` and `I=0.5A`.

`=>P=(6V)(0.5A)`

`=>P=3W`

Where one watt is equivalent to one joule per second. One volt is equivalent to one joule per coulomb, and one ampere is equivalent to one coulomb per second, so we can confirm that the units work out.
