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?
Expert Answer
hile discussing NTC thermistors; Technician A says that some systems use this type of thermistor as a protection device. Technician B says that when there is high current in a circuit, the resistance of the thermistor increases and causes a decrease in current flow. Who is correct?
The circuit breaker at a power seat motor continuously trips: Technician A says that this could be caused by a seat track problem that is causing mechanical resistance. Technician B says that this could be caused by corrosion at the motor, which is causing electrical re-sistance. Who is correct?
