If a centre tap transformer is used with two p-n junction diodes for full wave rectification then output voltage of rectifier with respect to each diode is (secondary voltage of transformer )
Options:
Answer:
Solution:
In a center-tap transformer used for full-wave rectification, the secondary winding is divided into two equal halves by the center tap.
If the total voltage across the secondary winding of the transformer is , the voltage across each half of the secondary winding is .
During each half cycle of the AC input, only one half of the secondary winding provides power to the load through its corresponding forward-biased diode.
Therefore, the output voltage of the rectifier, which is the voltage across the load, is equal to the voltage across half of the secondary winding, which is .
