A particular circuit is made up of a battery, a switch, a buzzer, and wires connecting the components. All of the components are in working order, but the buzzer does not make noise. Which statement explains this observation?

Question

• The switch is open.
• The load cannot convert electrical energy.
• The circuit lacks a power source.
• The conductors are not attached.

Answer 1

The statement that explains why the buzzer does not make noise is:

• The switch is open.

When the switch is open, it breaks the circuit, preventing electrical current from flowing through the circuit to power the buzzer, which is why it does not make noise.
