SUMMARY
The voltage across a broken lamp in a circuit can be measured as 12V due to the assumption of infinite resistance for the broken lamp. In this scenario, the intact lamp has a significantly lower resistance, causing the majority of the voltage to appear across the broken lamp. The first voltmeter reads 0V because there is no current flowing through the broken lamp, while the second voltmeter measures the full supply voltage of 12V across the broken lamp. This understanding is crucial for analyzing voltage distribution in series circuits.
