Question

in reverse bias, the current through an ideal diode is approximately: low, zero, high, very low. in a full - wave rectifier using ideal diodes at a bridge configuration, what is the voltage drop across the diodes during conduction? equal to the input voltage, two times the diodes forward voltage (2×0.7v for silicon diodes = 1.4v), four times the diodes forward voltage, zero

Explanation:

1. For an ideal diode in reverse - bias, it acts as an open - circuit, so the current through it is zero.
2. In a full - wave rectifier with ideal diodes in bridge configuration, ideal diodes have no voltage drop during conduction as they are assumed to have zero resistance when conducting.

Answer:

1. Zero
2. Zero
