To solve the problem we must know about resistance and power.
What is resistance?
Resistance is defined as the measurement that provides opposition to the current that travels through it.
It is given by the formula,
[tex]\rm Resistance = \dfrac{Voltage}{Current}[/tex]
The power of the washer is 1,800 watts.
Given to us
Current, I = 15 A
Voltage, V = 120V
Resistance Provided by the Washer
Using the formula of resistance to find the resistance,
[tex]\rm Resistance = \dfrac{Voltage}{Current}[/tex]
[tex]\rm Resistance = \dfrac{120\ V}{15\ A} = 8\ \Omega[/tex]
Thus, the resistance for the circuit will be 8 ohms.
Power of the washer
[tex]\rm Power = (Current)^2 \times Resistance[/tex]
[tex]P = I^2 R\\\\P = (15)^2\times 8\\\\P = 1,800\ \rm watt[/tex]
Hence, the power of the washer is 1,800 watts.
