Answer to Question #108931 in Electric Circuits for yosan tsegai

Question

describe how the equipment can be used to find the power of another battery charger

Answer 1

We have a battery charger. It consumes electrical power when it is charging batteries or when it is just connected to the mains circuit (in this case this is idle power).

Power is voltage times current.

Therefore, to find the power of a battery charger, we need to connect an ammeter in series with the charger and a voltmeter in parallel. Measurements will give us the values of the consumed current and voltage.
