A starting system voltage drop test is being done. Technician A says the higher the voltage drop, the lower the resistance in the circuit. Technician B says a high-voltage drop in the cranking circuit wiring can cause slow engine cranking. Which technician is correct?

1. Technician A only

2. Technicia B only

3. Both technian

4. Neithr A nor B

Respuesta :

Answer:

2. Technician B only

Explanation:

Given that a starting system voltage drop test is being done. Technician A says the higher the voltage drop, the lower the resistance in the circuit. Technician B says a high-voltage drop in the cranking circuit wiring can cause slow engine cranking. Which technician is correct?

1. Technician A only

2. Technicia B only

3. Both technian

4. Neithr A nor B

According to ohms law, the current is directly proportional to the voltage and inversely proportional to the resistance.

Increase in voltage drop will surely cause increased in resistance in the circuit.

Therefore, Technician A is not correct.

A drop in voltage will surely reduce the efficiency of a machine which will cause slow engine cranking.

Therefore, Technician B is correct.

So the right answer is 2 only B is correct.
