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
