Control Relay and Circuit Fundamentals Quiz

What is the primary characteristic of switches with definite states?

• They remain in the state they are set to.

• They are always in the off position.

• They change states automatically.

• They require no manual operation.

What is the role of contacts in devices like control relays?

• To change the voltage level.

• To open and close circuits.

• To act as a fuse.

• To provide power to the device.

What happens to a normally closed contact when the control relay coil is energized?

• It remains closed.

• It becomes a fuse.

• It opens.

• It changes voltage.

In the control relay circuit, what indicates where power is present?

• Blue color

• Green color

• Red color

• Yellow color

What happens to the contacts when power is removed from the control relay coil?

• They become permanently open.

• They remain in their energized state.

• They return to their normal position.

• They become permanently closed.

What is the purpose of using indicator lights in a control relay circuit?

• To provide additional power.

• To indicate the status of the circuit.

• To reduce circuit complexity.

• To increase circuit resistance.

What is the purpose of numbering wires in motor control circuits?

• To identify wire length.

• To indicate wire color.

• To ensure proper connections.

• To measure voltage.

When should you change the wire number in a motor control circuit?

• When crossing a component.

• When the wire changes color.

• When the wire is longer than 1 meter.

• When the wire is shorter than 1 meter.

What is the significance of A1 and A2 in a control relay coil?

• They determine the coil's size.

• They ensure correct polarity.

• They specify the coil's voltage.

• They indicate the coil's resistance.
