3 cards from this section. Quick, good the night before a test.
What is the peak value of an AC waveform if it reaches a maximum of 50V?
The peak value is the maximum voltage reached.
What is the RMS value if the peak value is 80V?
RMS is calculated by dividing the peak value by √2.
What is the peak value of an AC waveform?
Think about the highest point in a sine wave.
True or False: The average value of a full AC cycle is zero.
Consider how positive and negative areas of the waveform cancel out.
A generator produces an AC voltage with a peak value of 240V. Calculate the RMS value. Then, what is the average value for half a cycle?
Apply both formulas correctly to find the two values.
If a sinusoidal wave has a peak current of 60A, how much power does it deliver to a 20Ω resistor, considering the effective current?
Find the effective current first, then use the power formula.
