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

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

now,

R₀ = R_S + r_d

I_LM = V_sm – V_B /(R_S + r_d) + R_L

        = V_sm –V_B  

_{VLM = ILM . RL}

V_L(dc) = V_LM/π = 0.318V_LM

I_L(dc) = I_LM/π = 0.318I_LM

I_L = I_LMn/2 = 0.5I_LM = 0.5V_LM/R_L
