The peak inverse voltage (PIV) of a diode in a rectifier circuit is the maximum voltage the diode can withstand in the reverse bias. In the given scenario, assuming ideal diodes and without the specific details of Figure 1, the general approach to determine PIV is to consider the peak voltage of the AC source that the diode must block when it is reverse-biased. Since the exact configuration of the circuit (e.g., half-wave, full-wave, bridge rectifier) is not described, and without seeing Figure 1, it's challenging to provide a detailed explanation. However, a PIV of 42 V suggests a scenario where the diode needs to block a significant portion of an AC waveform, possibly in a full-wave rectification scenario where the peak voltage of the AC source is around 42 V. This value would be consistent with the peak voltage of the transformer's secondary winding in such a circuit, assuming the transformer does not step up or down the voltage significantly.
