Let

V_m = maximum value of transformer secondary voltage

V_s =rms value of secondary voltage

V_LM =maximum value of load voltage = V_sm – diode drop – secondary resistance drop

V_L = rms value of load voltage

V_L(ac) = rms value of ac component in the output voltage

I_L = rms value of load current

V_L(dc) =average value of load voltage

I_L(dc) = average value of load current

I_LM = maximum value of load current

R_L = load resistance

R_S = transformer secondary resistance

r_d = diode forward resistance

V_L = V_LM/√2 = 0.707 V_LM;

V_L(dc) = 2V_LM/ π = 0.636 V

V_L(ac) = √(V_L² – V_L(dc)²)

Similarly,

I_LM = V_LM/R_L; I_L = I_LM/√2 = 0.707 I_LM

I_L(dc) = 2I_LM / π = 0.636 I_LM ; I_L(ac) = √(I_L² – I_L(dc)²)

Incidentally, I_L(ac) is the same thing as I_r(rms)
