A full wave rectifier uses a capacitance of 60 μF in parallel with a ...
We have value of VRMS given here, so
=40
=40Thus, Vm = 56.56 V
Voltage Regulation is given by,
%Regulation = R/RL∗100%
where R is the resistance provided by transformer and the diode circuit, and RL is the load connected.
For a Full Wave rectifier with Capacitor filter, R is given as,
R = 1/4f0c = 83.33Ωand RL = 1000 Ω
Thus, Regulation provided by the configuration is 8.33 %.

A full wave rectifier uses a capacitance of 60 μF in parallel with a ...
Calculating Voltage Regulation
1. Given Parameters:
- Capacitance (C) = 60 μF
- Load resistance (R) = 1 kΩ
- Secondary voltage (V) = 40 V (RMS)
- Frequency (f) = 50 Hz
Calculating Ripple Voltage
2. The formula to calculate ripple voltage (Vr) in a full wave rectifier is:
Vr = (1 / (2*f*C)) * (V / (2 * sqrt(2)))
3. Substituting the given values:
Vr = (1 / (2*50*60*10^-6)) * (40 / (2 * sqrt(2)))
Vr ≈ 1.45 V
Calculating DC Output Voltage
4. The formula to calculate DC output voltage (Vdc) in a full wave rectifier is:
Vdc = (2 * V) / π
5. Substituting the given values:
Vdc = (2 * 40) / π
Vdc ≈ 25.46 V
Calculating Voltage Regulation
6. The formula to calculate voltage regulation in percentage is:
% Regulation = (Vr / Vdc) * 100
7. Substituting the calculated values:
% Regulation = (1.45 / 25.46) * 100
% Regulation ≈ 5.69%
Therefore, the voltage regulation provided by the full wave rectifier with the given parameters is approximately 5.69%. Hence, the closest option is 8.4%, which falls within the range of 5.69%.
