Control Relay and Ladder Diagram Quiz

What happens to the contacts of a control relay when the definite state switch is closed?

• The contacts open and disconnect all devices.

• The contacts become permanently closed.

• The contacts change state, affecting connected devices.

• The contacts remain unchanged.

In a ladder diagram, what is the effect of pressing a normally open push button connected to a red light?

• The red light turns on.

• The red light blinks.

• The red light turns off.

• The red light remains off.

How does a normally closed push button behave in a circuit?

• It never passes power.

• It continuously passes power until pressed.

• It blocks power until pressed.

• It passes power only when pressed.

Why are outputs typically wired in parallel in a circuit?

• To increase the voltage.

• To prevent voltage drops.

• To simplify the circuit design.

• To reduce the current.

What is the advantage of wiring inputs in series-parallel configurations?

• It simplifies the circuit layout.

• It reduces the number of inputs needed.

• It allows for more complex control logic.

• It increases the power consumption.
