The resistance of which type of resistor depends on light intensity.

The resistance of which type of resistor depends on pressure.

What is this component designed to do in a circuit?

Which of these components is NOT an output component

Sense when there is a temperature change.

The battery has been changed so the circuit works.

The battery has been switched around so the circuit works.

The switch is on, allowing the electrical energy to flow around the circuit.

Why does the light switch on in the second circuit?
