A toaster is plugged into a 120-volt household circuit. It draws 5 amps of

current.

AWhat is the resistance of the toaster?
BWhat is the power of the toaster in watts?
CWhat is the power in kilowatts?

Verified Answer :

AResistance R is a fraction of voltage over current:
\(R=\frac{U}{I}=\frac{120V}{5A}=24Ohm\)

b. The power of the toaster P is a multiplication of voltage:
\(P=U*I=120V*5A=600W\)

c. 1 kW = 1000W then:
\(P_{kW}=0,6kW\)

The resistance of the toaster is 24 ohms.

The power of the toaster in watts is 600 W.

The power in kilowatts is 0.6 KW.

What is the resistance of the toaster?

The resistance of the toaster is fraction of voltage over current.

R = V/I

R = 120/5

R = 24 ohms

What is the power of the toaster in watts?

The power of the toaster is a multiplication of voltage and current.

P = VI

P = 120*5

P = 600 W

What is the power in kilowatts?

1 kW = 1000W

P = 600/1000

P = 0.6 KW
