GS&EI ElectEngg 14 2024 1601-2025 The voltage division principle applies when voltmeters are connected in series. The voltage across each voltmeter is proportional to its internal resistance. A voltmeter with higher internal resistance will measure a higher voltage, up to its full- scale range.
If two 500 V full-scale voltmeters V, and V, having resistances 200 kΩ/V and 250 kΩ/V, respectively, are connected in series to measure 900 V, then - V, and V, read 400 V each
