Question

A clothes dryer uses about 9 amps of current from a 240 volt line. How much power does it use?

Answer 1

240 x 9 = power
power= 2160 watts

Answer 2

Power used by dryer is 2160 watts

Step-by-step explanation:

It is given that,

Current used by clothes dryer, I = 9 amps

Voltage used by dryer, V = 240 volts

We have to find the power used by it. Mathematically, the relationship between voltage, current and power is given by :

`P=V* I`

Putting the values of I and V in above equation as :

`P=240\ V* 9\ A`

P = 2160 watts

Hence, the power used by dryer is 2160 watts.
