Step-by-step solution
3 stepsDefine Form factor (2.1.1)
The form factor is the ratio of the RMS (Root Mean Square) value to the average value of an alternating current or voltage waveform. For a sinusoidal waveform, its value is approximately 1.11.
Define RMS value (2.1.2)
The RMS (Root Mean Square) value of an alternating current or voltage is the effective value that produces the same amount of heat in a given resistor as a constant direct current or voltage of the same magnitude over the same period of time.
Explain the term power factor (2.2)
The power factor in an AC circuit is the ratio of the real power (active power) consumed
