A half wave rectifier has a load resistance of 1.2 KΩ and peak ac voltage is 320 V. The root mean square value of current I_s, if R_f = 100 Ω, where the symbols have their usual meaning.

A 10V regulated DC power supply has a regulation of 0.002. Find the magnitude of variation in output voltage

An input voltage as shown is applied to the given circuit, which produces a half-wave rectified output.
 
Determine the percentage drop in the dc level, if the ideal diode is replaced by a silicon diode.

Consider the circuit shown in the figure below

The zener diode has a zener breakdown voltage of V_z = 10V and has the maximum amount of zener current I_z(max) = 20 mA. The zener diode turns on when the voltage of 10V is applied over it with nearly zero Knee current, then the value of load resistance R_L for proper regulation should be in the range

The load resistance of a centre-topped full-wave rectifier is 500Ω and the necessary voltage is 60 sin (100 πt). Peak, average and RMS value of current are respectively (given forward resistance is 50 Ω)
