Question

A camcorder has a power rating of 16 watts. If the output voltage from its battery is 8 volts, what current does it use?

Answer 1

Power is defined as product of current multiplying voltage, that is

P=I×V

Here, P is the power,

I is the current

While V is the voltage

Here,

P is 16 watt

V is 8 volt

I is the current, that needs to be determined,

Putting the values in the equation

16=I× 8

`I=(16)/(8)`

I=2

So, When a camcorder has a power rating of 16 watts. If the output voltage from its battery is 8 volts, what current is 2 A

Answer 2

The equation for power is,

Power
`P = I * V`

Where P is power is Watts

I is current in Amperes

V is voltage in volts

Given, power of the camcorder = 16 Watts

Output voltage from its battery = 8 Volts

Calculating the current in Amperes from power and voltage,

`P = I * V`

`16 Watts = I * 8 Volts`

`I =(P)/(V)`

I =
`(16 W)/(8 V)`

= 2 A

Therefore the current used will be 2 A.
