You notice that when you turn off your bedroom lights, the kitchen lights can stay on. Based on this observation, what kind of circuit was used to wire the lights in your house? A. Parallel circuits because there are two or more paths for the current to flow. B. Series circuits because the current through each component is the same. C. Series circuits because there are two or more paths for the current to flow. D. Parallel circuits because the current through each component is the same.

the correct answer is A

Explanation:

In a series circuit the current flows through the circuit and when it is opened at some point the current stops throughout the circuit.

In a parallel circuit, the current flows through the different branches of the circuit and when the current in one branch is interrupted, it continues to flow through the others.

In this exercises they indicate that the bedroom lights are turned off (the circuit was opened), but the kitchen lights are still on, therefore it is a parallel circuit with at least two branches, the current that circulates through each one depends on the existence on each branch.

Therefore the correct answer is A
