Capacitor Filter
The correct answer is option B: It is electrolytic.
Explanation:
A capacitor filter is an electronic circuit that is used to filter out the AC components from the rectified output of a power supply. It consists of a capacitor connected in parallel to the load.
Key Points:
- Capacitor Output Filter: The capacitor filter is also called a capacitor output filter because it is connected at the output of the rectifier circuit to filter the rectified output.
- Electrolytic Capacitor: The capacitor used in the capacitor filter is an electrolytic capacitor. Electrolytic capacitors are widely used in power supply circuits due to their high capacitance values and ability to handle high voltage levels.
- Connected in Parallel: The capacitor filter is connected in parallel to the load. This means that the load current passes through the capacitor. The capacitor charges during the positive half-cycle of the input AC voltage and discharges during the negative half-cycle, thereby smoothing the output voltage.
- Filtering AC Components: The main purpose of the capacitor filter is to filter out the AC components from the rectified output. During the positive half-cycle, the capacitor charges and stores energy, which helps in maintaining a relatively constant output voltage during the negative half-cycle when the rectified output is zero or negative.
Conclusion:
In summary, the capacitor filter is an electrolytic capacitor connected in parallel to the load in a power supply circuit. It helps in filtering out the AC components from the rectified output, thereby smoothing the output voltage.
