Question

A camcorder has a power rating of 13 watts. If the output voltage from its battery is 6 volts, what current does it use?

Answer 1

Power = (voltage) x (current)

13 watts = (6 volts) x (current)

Divide each side by (6 volts):

Current = (13 watts) / (6 volts)

Current = (13/6) Amperes

Current = 2.17 Amperes
