Question

a component of a circuit changes, as shown below. how would this change affect the electric circuit? a switch is closed, so the circuit would be incomplete and broken and the lights in the circuit would not shine. a switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. a switch is opened, so the circuit would be incomplete and broken and the lights in the circuit would not shine. a switch is opened, so the circuit would be complete and unbroken and the lights in the circuit would shine.

Explanation:

A switch is a component in a circuit. When a switch is closed, it allows the electric current to flow through the circuit, making the circuit complete. When the circuit is complete, the lights (if present) in the circuit will shine as the current can pass through them. In the given diagram, the change shows a switch being closed (the initial state has a break which is removed in the final state, similar to a switch being closed).

Answer:

B. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.
