Day#16

What is the role of a filter capacitor in a charger?

• Amplifies voltage

• Charges battery directly

• Smooths the pulsating DC

• Protects diode

What happens if the filter capacitor is removed?

• Voltage increases

• Output becomes unstable (ripples)

• Output improves

• LEDs glow steadily

What kind of current is used in homes?

• DC

• AC

• Pulsating

• Static

Which is NOT a function of a capacitor?

• Store energy

• Convert AC to DC

• Smooth DC output

• Act as a filter

Why is working directly with AC dangerous?

• It doesn’t power devices

• It can cause shock or fire

• It's too slow

• It has low current

What happens if a diode is reversed in a rectifier?

• It blocks current in the wrong direction

• It amplifies current

• It smooths voltage

• It regulates power

In Tinkercad, we simulate AC using:

• Function Generator

• Battery

• AC source directly

• Motor

Which component must always match polarity?

• Switch

• Polarized capacitor

• Transformer

• Ceramic Capacitor

What does a charger output?

• AC

• DC

• Magnetic field

• Sound

What is ripple in DC output?

• Current increase

• Small fluctuations in DC voltage

• Loud sound

• High resistance
