Answer: ________ Units:__________

Answer 1

Answer: The current use by the camcorder is of  2.42 amperes.

Explanation:

Power rating of the camcorder,P = 17 watt

The voltage from the battery,V = 7 volts

$Power=Voltage\times Current$

$17 watts=7 volts\times I$

$I=\frac{17 watts}{7 Volts}=2.42 Ampere$

The current use by the camcorder is of  2.42 Amperes.
