Assertion (A): Bridge arrangement is preferred over centre-tapped transformer arrangement for full-wave rectification.
Reason (R): The bridge arrangement improves the filtering action.
The correct answer is option 'C' - A is true but R is false.
Explanation:
To understand why the correct answer is option 'C', let's examine both the assertion and the reason separately.
Assertion (A): Bridge arrangement is preferred over centre-tapped transformer arrangement for full-wave rectification.
In a full-wave rectifier, the AC input voltage is converted into a pulsating DC voltage. There are two common configurations used for full-wave rectification - the centre-tapped transformer arrangement and the bridge arrangement.
- In the centre-tapped transformer arrangement, the secondary winding of the transformer is center-tapped, and two diodes are connected to the ends of the winding. This arrangement utilizes only half of the transformer winding at a time, resulting in a lower overall efficiency compared to the bridge arrangement.
- In the bridge arrangement, four diodes are connected in a bridge configuration. This arrangement allows the full secondary voltage to be utilized, resulting in a higher efficiency compared to the centre-tapped transformer arrangement. The bridge arrangement also eliminates the need for a center-tapped transformer.
Therefore, the bridge arrangement is preferred over the centre-tapped transformer arrangement for full-wave rectification due to its higher efficiency and the absence of a center-tapped transformer.
Reason (R): The bridge arrangement improves the filtering action.
This reason is not valid. The filtering action in a rectifier circuit is primarily determined by the presence of a filter capacitor, not the arrangement of diodes. Both the centre-tapped transformer arrangement and the bridge arrangement can incorporate a filter capacitor to smooth out the output voltage.
The bridge arrangement itself does not inherently improve the filtering action compared to the centre-tapped transformer arrangement. The filtering action depends on the capacitance value of the filter capacitor and the load connected to the rectifier circuit.
In conclusion, while the assertion is true, the reason is false. The bridge arrangement is preferred for full-wave rectification due to its higher efficiency, but it does not directly improve the filtering action compared to the centre-tapped transformer arrangement.
Reason (R): The bridge arrangement improves the filtering action.
The correct answer is option 'C' - A is true but R is false.
