The circuit is working, and all three bulbs are lit. If a switch at C is opened, what will happen to the circuit?
2 answers:
The correct answer is option <span>D. All three bulbs will go out.
</span>
In the circuit, all the bulbs are connected in series with each other. When the <span>switch at C is opened, the circuit is broken (consider the wire is broken). It is shown in diagram as well (attached).
Hence, when the circuit is broken, the current will not reach the bulbs 2 & 3. And, the connection will be disrupted, So all the bulbs will blow out.
Hence, D is the correct option. </span>
