Which of the following is a correct representation of peak value in an AC circuit?
Answer:
In an AC (alternating current) circuit, the peak value represents the maximum value reached by the alternating current or voltage over a full cycle. The peak value is equal to the amplitude of the wave or signal. In mathematical terms, the peak value is defined as the maximum absolute value of a function.
In terms of calculation, if given the peak-to-peak value (which is the difference between the positive peak and negative peak values), you can find the peak value by dividing the peak-to-peak value by 2.
It is important to note that the peak value is different from the RMS (Root Mean Square) value of an AC signal. The RMS value is used to compare AC signals with DC signals, as it represents the equivalent DC value that would produce the same amount of heat in a resistor.
Therefore, in summary, the peak value in an AC circuit is the maximum value reached by the alternating current or voltage during a cycle, equivalent to the amplitude of the wave.
