Biasing Thyristors Quiz

What happens when a thyristor is forward biased?

• It allows the current to flow through it.

• It emits a sound.

• It changes color.

• It stops the current from flowing through it.

How does forward biasing affect the conduction of a thyristor?

• Forward biasing decreases the resistance of the thyristor, allowing it to conduct current.

• Forward biasing causes the thyristor to switch off completely.

• Forward biasing has no effect on the conduction of the thyristor.

• Forward biasing increases the resistance of the thyristor, preventing it from conducting current.

What happens when a thyristor is reverse biased?

• It allows the current to flow freely

• It acts as a closed switch

• It has no effect on the current flow

• It blocks the current flow and acts as an open switch.

How does reverse biasing affect the conduction of a thyristor?

• Reduces conduction

• Increases conduction

• Causes the thyristor to switch off

• Has no effect on conduction

What is the purpose of gate triggering in thyristors?

• To play music

• To cook food

• To control the weather

• To control the turn-on and turn-off of the device

How does gate triggering affect the conduction of a thyristor?

• It increases the resistance of the thyristor

• It causes the thyristor to overheat and malfunction

• It has no effect on the conduction of the thyristor

• It allows the thyristor to switch from the off state to the on state.

What is latching current in thyristors?

• The current at which the thyristor switches from off to on state

• The current at which the thyristor switches from on to off state

• Maximum current required to keep the thyristor in the off state

• Minimum current required to keep the thyristor in the on state

How does latching current affect the conduction of a thyristor?

• Latching current causes the thyristor to turn off immediately

• Latching current allows the thyristor to remain in the on state even after the gate current is removed.

• Latching current increases the gate current required to turn on the thyristor

• Latching current has no effect on the conduction of a thyristor
