FILTER AND REGULATOR

The circuit is used to reduce the voltage difference to zero or at least to a minimum value.” The statement refers to ______________________ circuit.

• Rectifier

• Regulator

• Filter

• Transformer

Identified which one is NOT the type of filter

• C filter

• LC filter

• 
• RLC filter

State the function of filter circuit in Linear DC Power Supply unit .

• To convert the AC voltage from the wall outlet to a lower voltage.

• To maintain a constant power supply output voltage

• To reduce the variations in the output of the rectifier

• To rectify the AC voltage to DC voltage

The ripple from the filter can be redused further by:

• Increasing the capacitor value

• Reducing the capacitor value

• Placing a zener diode in the circuits

• Placing a series transistor in the circuit
