### Understanding Electric Circuits with Parallel Lamps#### Problem Statement:A battery is connected to three identical lamps. A voltmeter is connected across one of the lamps. If the filament in lamp X breaks, the reading on the voltmeter will#### Circuit Diagram Explanation:- The circuit consists of a battery that provides the electric power.- Three identical lamps are connected in parallel to the battery.- A voltmeter (denoted by the letter V) is connected across one of the lamps to measure the voltage drop across it.- Lamp X is identified as the one whose filament is suspected to break.#### Multiple Choice Question:If the filament in lamp X breaks, the reading on the voltmeter will- ○ become zero- ○ decrease- ○ stay the same- ○ increase#### Analysis:Breaking the filament in lamp X means that the lamp will no longer conduct electricity and will effectively become an open circuit. In a parallel circuit:1. The voltage across all parallel components remains the same as the voltage of the power source.2. If one of the lamps (in this case, lamp X) breaks, the other lamps continue to receive the same voltage from the battery.#### Conclusion:Based on the properties of parallel circuits, if lamp X breaks, the voltage across the other lamps will not change. Therefore, the reading on the voltmeter, which is connected across one of the functioning lamps, will:- **Stay the same**.This is because the voltmeter is directly measuring the voltage that the battery supplies, which remains unchanged even if one of the parallel lamps breaks.---This explanation is designed to help students understand the behavior of parallel circuits and the implications of a component failure within such circuits.

According to the Ohm's law, the voltage drop across a circuit is defined as the product of the…
