Question 1

The strength of an electromagnet is dependent on _____.
A) the number of coil windings [length of the conductor]
B) the amount of current [amps] passing through the coil
C) both "the number of coil windings [length of the conductor]" and "the amount of current [amps] passing through the coil"
D) neither both "the number of coil windings [length of the conductor]" nor "the amount of current [amps] passing through the coil"

Accepted Answer

The strength of an electromagnet is determined by both the number of coil windings and the amount of current passing through the coil. More windings and higher current increase the magnetic field strength.

Question 2

If the driving gear has 11 teeth and the driven gear has 44 teeth, the gear ratio equals ____________________ to 1.

Accepted Answer

The answer of If the driving gear has 11 teeth...

Question 3

Technician A says kinetic energy in the crankshaft is converted into electrical energy by the generator. Technician B says electrical energy in the generator is converted into chemical energy in the battery. Who is correct?
A) A only
B) B only
C) both A and B
D) neither A nor B

Accepted Answer

Both technicians are correct. The alternator (generator) converts the kinetic energy from the engine into electrical energy that is used to charge the battery. The battery then stores the electrical energy in the form of chemical energy.
