Question 1

What is an ‘Oscilloscope’?

Answer 1

A Device Called an Oscilloscope is Used to Show how the Potential Difference Generated in the Coil Changes Over Time.

Question 2

What is Displayed on the Screen of an Oscilloscope to Represent the Potential Difference Generated in the Coil Over Time?

Answer 2

A Line, Called a Trace.

Question 3

What does the Vertical Axis of the Trace on an Oscilloscope Represent?

Answer 3

The Generated Potential Difference.

Question 4

What does the Horizontal Axis of the Trace on an Oscilloscope Represent?

Answer 4

Time.

Question 5

An Alternator Consists of…

Answer 5

A Rotating Magnet next to / inside of a Coil.

Question 6

A Dynamo Consists of…

Answer 6

A Coil, which is Rotated by a Mechanical Process, Inside of a Magnetic Field.

Question 7

In the Generator Effect, when the Coil is Physically Parallel to the MFL, the Current Flowing Through it is Flowing ___ to the MFL, so it Cuts Through them, Inducing a PD, or Current, to the Coil.

Answer 7

Perpendicular.

Question 8

In the Generator Effect, when the Coil is Physically Perpendicular to the MFL, the Current Flowing Through it is Flowing ___ to the MFL, so it doesn’t Cut Through them, so a PD, or Current, is not Induced/Supplied to the Coil.

Answer 8

Parallel.
