AC Waveform Quiz

What is the unit of frequency?

• Ohm (Ω)

• Hertz (Hz)

• Volt (V)

• Ampere (A)

What does the peak value represent in an AC waveform?

• The period of the waveform

• The root mean square value

• The maximum voltage or current

• The average value

What is the relationship between frequency and period?

• Frequency is directly proportional to period

• Frequency is inversely proportional to period

• Frequency is unrelated to period

• Frequency equals period

What is the formula for root mean square (RMS) voltage?

• Vrms = √(Vp^2 + Vp^2)

• Vrms = Vp / 2

• Vrms = 2Vp

• Vrms = Vp / √2

In an AC circuit, what does the term 'phase shift' refer to?

• The average value of current

• The time taken for one complete cycle

• The difference in phase between two waveforms

• The maximum value of voltage

What is the unit of capacitance?

• Hertz (Hz)

• Ohm (Ω)

• Farad (F)

• Henry (H)

What is the average value of a complete AC waveform?

• The peak-to-peak value

• The RMS value

• The peak value

• Zero

What does the term 'peak-to-peak value' refer to?

• The time period of the waveform

• The value from the positive peak to the negative peak

• The average value of the waveform

• The RMS value

What is the phase difference when two waveforms are in phase?

• 180 degrees

• 90 degrees

• 0 degrees

• 360 degrees

What is the symbol for peak current in an AC waveform?

• Vp

• Ip

• Vpp

• Irms
