Half-Wave Rectifier: Average Output Voltage (V_dc = V_m / π)

jee-mainneet-ug

V_dc = V_m / π

What each symbol means

SymbolWhat it stands for
V_mPeak voltage of AC input (V)
V_dcAverage (DC) output across load (ideal diode, resistive load)

When to use this

Single diode, sinusoidal input, conduction half-cycle only; ideal diode; resistive load.
