Answer:
16Ω
Explanation:
According to Ohm's law, the voltage (V) passing across a device is related to the current (I) flowing through it as follows;
V = I x R -------------------(i)
Where;
R = the resistance of the device
According to the question, the device is the heater and it has the following details;
V = operating voltage = 120V
I = current = 17.5A
Now, substitute these values into equation(i) as follows;
120 = 17.5 x R
Solve for R;
R = [tex]\frac{120}{7.5}[/tex]
R = 16Ω
Therefore, the resistance of the heater is 16Ω
