Technician A says that a 12-volt light bulb that draws 12 amps has a power output of 1 watt Technician B says that a motor that has 1 ohm of resistance has a power rating of 144 watts if it is connected to a 12-volt battery. Who is correct? Technician A Technician BBoth A and BNeither A nor B

To determine

The technician with correct approach.

Explanation

Given:

Technician A says that a 12-volt light bulb that draws 12 amps has a power output of 1 watt.

Technician B says that a motor that has 1 ohm of resistance has a power rating of 144 watts if it is connected to a 12-volt battery.

According to Watts law, Power (P)=i×V

According to Ohm’s law, i=vr

Where, i = current

v = voltage and

r = resistance

Now by putting value of’ i’ in above equation, we get,

P=Vr×
