When all switches in the circuit are in the off position, the circuit is open, meaning that no current will flow through any of the components. This changes the analysis significantly:

A. Peak Voltage at the Secondary Side

The peak voltage at the secondary side is determined by the transformer's operation, which is independent of whether switches are on or off. The secondary side voltage depends on the primary side voltage and the turns ratio of the transformer.

From the previous analysis, the peak voltage at the secondary side is:

$V_{peak_{secondary}} = 74.67 \text{ V}$

Answer for A: The Peak Voltage at the secondary side is 74.67 V (unchanged).

B. RMS Value at the Secondary Side

Similarly, the RMS value at the secondary side is also determined by the transformer ratio, independent of the switches.

From the previous analysis:

$V_{rms_{secondary}} = 52.8 \text{ Vrms}$

Answer for B: The RMS value at the secondary side is 52.8 Vrms (unchanged).

C. Value of RL (Load Resistance, RL)

The load resistance $R_L$ is determined by the components connected in the circuit. With all switches off, there may not be a complete circuit allowing current to flow through $R_L$, but its value as a resistor remains the same as calculated before:

$R_L = 888.89 \text{ ohms}$

Answer for C: The value of RL is 888.89 ohms (unchanged).

D. Current Running in RL

With all switches off, the circuit is open, and no current can flow through $R_L$. Therefore, the current through $R_L$ is:

$I_{RL} = 0 \text{ A}$

Answer for D: The current running in RL is 0 A.

E. Output Voltage of RL

With no current flowing in the circuit due to the switches being off, the voltage across $R_L$ would be zero because there's no potential difference being created across it:

$V_{RL} = 0 \text{ V}$

Answer for E: The output voltage of RL is 0 V.

Summary of Answers

• B. RMS value at the secondary side: 52.8 Vrms
• C. Value of RL: 888.89 ohms
