Question

in this series circuit, the switch is closed and all three bulbs are lit what happens if the switch is opened? all bulbs will go out all bulbs will stay lit

Explanation:

Step1: Analyze series circuit characteristics

In a series circuit, the current has only one path. When the switch is closed, current flows through all bulbs, lighting them. When the switch is opened, the circuit is broken.

Step2: Determine bulb state

Since the circuit is broken (no complete path for current), no current can flow through any of the bulbs.

Answer:

all bulbs will go out
