Alternating currents and transformers (9)

Question 1

Frequency of a waveform

Answer 1

number of complete waves per second, measured in Hz.

Question 2

Eddy currents

Answer 2

generated in metal sheets by changes in magnetic flux. Eddy currents transfer electrical energy to heat energy.

Question 3

Peak voltage

Answer 3

is half the peak-to-peak voltage, and is equivalent to the amplitude of the waveform.
