You have three light bulbs. All have the same intensity when lit. Explain how you can determine that they are connected in parallel by unscrewing one light bulb. In your response, state the relationship between the current and resistors in parallel.

Originally Answered: You have three light bulbs ... A parallel circuit means that the current flows through all the loads (light bulbs in this question). Since the current is connected to each of them, disconnecting (unscrewing) one of them will still allow the current to flow to the other two and they will remain lit.
