Question 1 of 10
Which of the following is a key function of both diodes and SCRs?
Both diodes and SCRs are used as switches, controlling the flow of current in a circuit.
Question 2 of 10
How many terminals does a standard diode have?
A diode has two terminals: Anode and Cathode.
Question 3 of 10
What is the primary function of a diode?
Diodes are primarily used for rectification, converting AC to DC.
Question 4 of 10
Which terminal of an SCR is used for triggering (turning it on)?
The Gate terminal is used to trigger or fire the SCR.
Question 5 of 10
How many layers of semiconductor material are typically used to construct an SCR?
An SCR is made of 4 layers of semiconductor material (PNPN structure).
Question 6 of 10
In what bias condition does a diode conduct current?
A diode conducts current in forward bias.
Question 7 of 10
Which of the following is a type of diode?
LED (Light-Emitting Diode) is a type of diode.
Question 8 of 10
How many PN junctions does an SCR typically have?
An SCR has 3 PN junctions.
Question 9 of 10
What does SCR stand for?
SCR stands for Silicon Controlled Rectifier.
Question 10 of 10
Which of the following describes the current flow in an SCR?
An SCR allows current to flow in only one direction, making it unidirectional.
