Question

A camcorder has a power rating of 11 watts. If the output voltage from its battery is 3 volts, what current does it use? amps

Answer 1

Answer:

3.67 A

Explanation:

The power rating is related to the voltage and the current by the following equation:

$P=VI$

where

P is the power rating

V is the voltage

I is the current

In this situation, we have:

P = 11 W

V = 3 V

I = ?

So, we can re-arrange the equation to calculate the current used:

$I=\frac{P}{V}=\frac{11 W}{3 V}=3.67 A$

Answer 2

Current = Power/Voltage. 11W/3v = 3.67Amps
