Introduction to AC System Quiz 1

What are the different types of waveform in AC system?

• upward wave, downward wave, leftward wave, and rightward wave

• circle wave, hexagon wave, octagon wave, and pentagon wave

• positive wave, negative wave, neutral wave, and ground wave

• sine wave, square wave, sawtooth wave, and triangular wave

What is peak voltage in a sinusoidal waveform?

• Minimum voltage reached during one complete cycle

• Voltage at the midpoint of one complete cycle

• Maximum voltage reached during one complete cycle

• Average voltage over one complete cycle

How is peak to peak voltage calculated in an AC system?

• By adding the maximum positive voltage and the maximum negative voltage

• By multiplying the maximum positive voltage and the maximum negative voltage

• By dividing the maximum positive voltage by the maximum negative voltage

• By finding the difference between the maximum positive voltage and the maximum negative voltage.

What is the RMS value of a sinusoidal waveform?

• Peak value divided by the square root of 2

• Average value divided by 2

• Peak value multiplied by 2

• Peak value minus the square root of 2

Explain the concept of average value in an AC system.

• Mean value of the voltage or current over a complete cycle

• Maximum value of the voltage or current over a complete cycle

• Sum of all the voltage or current values over a complete cycle

• Minimum value of the voltage or current over a complete cycle

What is the period of a sinusoidal waveform?

• The period of a sinusoidal waveform is the amplitude of the waveform.

• The period of a sinusoidal waveform is the frequency of the waveform.

• The period of a sinusoidal waveform is the time it takes for the waveform to complete one full cycle.

• The period of a sinusoidal waveform is the phase of the waveform.

How is frequency related to the period in an AC system?

• Unrelated

• Constant

• Inverse

• Directly proportional
