SCR Components Quiz

What does SCR stand for?

• Silicon Controlled Rectifier

• Silicon Capacitor Resistor

• Silicon Current Regulator

• Silicon Controlled Resistor

Which component of SCR is responsible for controlling the flow of current?

• anode

• cathode

• emitter

• gate

What is the purpose of the gate signal in SCR?

• To prevent current flow through the SCR

• To regulate the voltage across the SCR

• To protect the SCR from overheating

• To control the triggering of the SCR and allow current flow through it.

What happens when the gate signal is not applied to SCR?

• The SCR will conduct current and remain in the on state.

• The SCR will not conduct current and will remain in the off state.

• The SCR will conduct current but will be in an unstable state.

• The SCR will conduct current but will not change state.

What is the function of the anode in SCR?

• To provide a positive terminal for the flow of current.

• To control the speed of the motor.

• To regulate the voltage in the circuit.

• To provide a negative terminal for the flow of current.

What is the function of the cathode in SCR?

• To generate heat when the gate signal is applied

• To regulate the voltage across the SCR

• To emit electrons when the gate signal is applied

• To block the flow of electrons when the gate signal is applied

What is the function of the gate in SCR?

• To regulate the voltage across the device.

• To amplify the current through the device.

What is the function of the heat sink in SCR?

• To dissipate heat

• To amplify heat

• To insulate heat

• To generate heat

What is the function of the snubber circuit in SCR?
