Why is AC waveform called an alternating waveform? Explain the generation of the AC waveform with a diagram. Define the following parameters of AC waveform: Total time (T), Frequency (F), Maximum Voltage (Vm), Angular velocity (ω). Write an equation of the AC waveform and state each term of the equation. Define with equation: Average value, RMS value, Form factor, Peak factor of AC waveform. AC voltage waveform changing up to 15 V of its maximum value. Calculate its: Average voltage (Vavg), RMS voltage (Vrms). If the frequency of the AC waveform is 50 Hz and maximum voltage is 200 V, calculate an instantaneous voltage at instantaneous time t = 50 ms. What is meant by phase difference angle (θ) of AC waveforms? Define in phase and out of phase of AC waveforms with figures of waveforms. The equation of the instantaneous voltage is v = 100 sin 314t. Find out: RMS voltage, Average voltage, Frequency. Define the Leading and Lagging waveforms with a diagram. What is meant by Power of the AC waveform? State the features of Active, Reactive, and Apparent power of AC waveform. Compare active power (P) with reactive power (Q). Compare active power (P) with apparent power (S). Define power factor. Explain 'power triangle' with a diagram.
