In the bathroom of your house you would like to run a 300 W hot wax heater, a 30 W electric razor, a 1080 W curling iron, and four 120 W lights. Assuming your house is wired for 120 Volts, how much current will be pulled by these electrical devices

12.75 A

Explanation:

Current: This can be defined as the rate of flow of electric charge in a circuit. The S.I unit is Ampere (A)

P = VI  Equation 1

Where P = power, V = Voltage, I = current.

make I the subject of the equation

I = P/V Equation 2

Total Power = 300+30+1080+120 = 1530 W.

Given: P = 1530 W, V = 120 V

Substitute into equation 2

I = 1530/120

I = 12.75 A.

Hence the current is = 12.75 A

the answer to your question is high voltage and high currency
