Semiconductor Diodes

Component that Convert AC to DC and allow current to flow in one Direction

• Capacitor

• Diode

• Inverter

• Resistor

Anode is _________ Polarity in diodes

• Negative

• Positive

• Ground

• Hot Side

Types of diodes used in lighting system and display

• LED

• zener diodes

• rectifier diodes

• schottky

What is the name of this Diode?

• PN junction

• LED

• silicon

• PNP

Diode has polarity

• anode and cathode

• on and off

• output and input

• none of the above

The region on either side of the junction which becomes free from the mobile charge carriers is called

• Energy gap region

• Charge free region

• Diffusion region

• Depletion region

Characteristics of a diode that helps in rectification

• Allows Unidirectional flow of current

• Allows Bidirectional flow of current

• Opposes the flow of current

• conducts in reverse biased

In the forward bias arrangement of a p-n junction diode,

• the n-end is connected to the positive terminal of the battery

• the p-end is connected to the positive terminal of the battery

• the direction of current is from n-end to p-end in the diode

• the p-end is connected to the negative terminal of the battery

which statement is correct? (the dark circles represent the electrons)

• p-type of the diode is connected to the negative terminal.

• Electron moves across the p-n junction, makes the diode forward biased

• current will not flow in the circuit

• reverse biased circuit

During formation of p-n junction

• an electron diffuses from n to p side

• a hole diffuses from p to n side

• a hole diffuses from n to p side

• an electron diffuses from p to n side
