linh builds a circuit from the diagram shown. if linh removes bulb 3, which bulbs will remain lit? 1 only 1 and 2 only 4 only 1, 2, and 4
Answer
Explanation:
Step1: Analyze circuit type
The circuit is a parallel - circuit. In a parallel circuit, each branch is independent of others.
Step2: Consider effect of removing bulb 3
Bulb 3 is in a separate parallel branch. Removing it will not affect the current flow through bulbs 1, 2, and 4 as they have their own independent paths for current.
Answer:
1, 2, and 4
