Q

What produces a turning movement in an electric motor?

A

An electric current and magnetic field

21
Q

Function of an armature?

A

Converts an electromagnetic energy to rotation

22
Q

Function of bearings?

A

support the drive shaft

23
Q

Function of brushes?

A

supply current to the armature

24
Q

Function of cummutator?

A

reversed the current to the armature

25
Q

Function of drive shaft?

A

Tranfers rotation from the motor

26
Q

Function of field windings?

A

create an electromagnetic field

27
Q

Components of an simple DC motor?

A

a field magnet and an armature

28
Q

Components of an armature?

A

Commutator and a loop of wire.

Commutator consists of brushes

29
Q

The piston moves down the cylinder?

A

This draws in fuel from the carburettor

30
Q

The piston creates a vacuum?

A

This creates a partial vacuum

31
Q

The piston moves up the cylinder?

A

This compresses the mixture.

32
Q

The gas expand quickly?

A

This pushes the piston down.

33
Q

The piston moves up and down?

A

This rotates the crankshaft.

34
Q

The crankshaft spins round?

A

This turns the rotor at 3000 rpm.

35
Q

The armature of the alternator rotates?

A

This induces a current in the stator windings.

36
Q

The alternator runs at a steady 3000 rpm?

A

This generates around 700 watts.

37
Q

6 stages in the distribution system?

A
  1. Electricity leaves the power plant.
  2. The voltage is increased at a step-up station.
  3. Transmission lines carry high-voltage electricity to different substations.
  4. Electricity is stepped down by transformers.
  5. Power levels are lowered by small transformers mounted on poles.
  6. Current at lower voltages is transmitted to homes and offices.
38
Q

Four strokes cycle?

A

Intake stroke -> compression stroke -> power stroke/expansion stroke -> exhaust stroke

39
Q

The piston moves down the cylinder?

A

This draws in fuel from the carburettor

40
Q

The piston creates a vacuum?
