To calculate the output voltage of the full wave rectifier circuit, we need to determine the voltage drop across the diodes.
Since each diode has an internal resistance of 1 ohm, the total resistance for the circuit will be 1 + 1 = 2 ohms.
The output voltage of the full wave rectifier circuit can be calculated using the formula:
Vout = Vin - 2 * Vd
Where:
Vout = Output voltage
Vin = Input voltage (40-0-40Vrms = 80Vrms)
Vd = Voltage drop across the diodes
Assuming a typical voltage drop of 0.7V for each diode, the total voltage drop across the diodes (Vd) will be 2 * 0.7V = 1.4V.
Plugging in the values:
Vout = 80Vrms - 2 * 1.4V
Vout = 80Vrms - 2.8V
Vout = 77.2Vrms
Therefore, the output voltage of the full wave rectifier circuit with a 40-0-40Vrms transformer and diodes with an internal resistance of 1 ohm is 77.2Vrms.
Since each diode has an internal resistance of 1 ohm, the total resistance for the circuit will be 1 + 1 = 2 ohms.

Vd = Voltage drop across the diodes
Assuming a typical voltage drop of 0.7V for each diode, the total voltage drop across the diodes (Vd) will be 2 * 0.7V = 1.4V.
Plugging in the values:
Vout = 80Vrms - 2 * 1.4V
Vout = 80Vrms - 2.8V
Vout = 77.2Vrms
Therefore, the output voltage of the full wave rectifier circuit with a 40-0-40Vrms transformer and diodes with an internal resistance of 1 ohm is 77.2Vrms.
