Hey,
How would you suggest I draw my diagrams for this question:
A student claims that a DC generator is an ‘electric motor in reverse’.
Analyse this claim with reference to the structure and function of a simple DC
generator and an electric motor.
Include diagrams in your answer.
THANK YOU
I'll assume you can handle the written part of the response.
For the diagrams, when you draw a DC motor and a DC generator, the bulk of the two diagrams should be identical. You will need an armature, commutator, brushes and the magnetic field in both cases.
The differences lie in thus:
In a motor, we convert electrical energy to kinetic energy. Because electrical energy is what's being converted, we need to draw a
battery (cell) connected in a closed circuit to the brushes.
In a generator, we convert kinetic energy to electrical energy. Somehow we must provide the (rotational) kinetic energy, so it really helps to draw an
axle for us to rotate. Also, because we usually use a generator to power something up, instead of a battery we will draw a
load (this could be a light bulb or many other things).
