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

The equation for power is,

Power

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,

I =

        = 2 A

Therefore the current used will be 2 A.

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=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
