Concept:Full-wave rectification routes both half-cycles through the load in a single direction, converting an alternating waveform into a unidirectional pulsating waveform.
Formula:$$I_L(t) = |I_m \sin(\omega t)|$$
Solution:- During the positive half-cycle, \( D_1 \) directs current downward through the load resistor.
- During the negative half-cycle, \( D_2 \) also directs current downward through the load resistor.
- Because current flows through \( R_L \) in the same direction throughout the entire cycle, the output voltage has a single polarity (\( \text{DC} \)).
Why other options are incorrect:- Option A: If current reversed direction every half-cycle, the output would remain alternating current (\( \text{AC} \)).
- Option B: Current flowing only during the positive half-cycle describes half-wave rectification.
- Option D: Conduction occurs during both half-cycles, not solely during the negative half-cycle.
