Day#15

What is the main function of a diode?

• Store charge

• Emit light

• Allow current in one direction only

• Convert AC to DC

What does a resistor do in a circuit?

• Increases voltage

• Blocks current completely

• Limits the current flow

• Converts AC to DC

Which component is polarity-sensitive?

• Resistor

• Ceramic capacitor

• LED

• Switch

The longer leg of an LED is called:

• Cathode

• Anode

• Terminal

• Ground

A capacitor is used to:

• Block all current

• Store and release electrical energy

• Emit light

• Boost voltage

What does a diode protect in a circuit?

• Voltage

• Components from reverse current

• Power supply

• LEDs from glowing

What happens if you reverse an LED?

• It glows brighter

• It stores charge

• It doesn't light up

• It explodes

What is the unit of resistance?

• Ampere

• Volt

• Ohm

• Watt

LEDs require a resistor in series to:

• Store power

• Prevent too much current

• Reverse direction

• Make the LED blink

Which of the following has polarity?

• Resistor

• Diode

• Switch

• Wire
