Concept:
The voltmeter sensitivity (Sv) is determined by dividing the sum of the resistance of the meter (Rm)
Mathematically, sensitivity is expressed as:
E = Rated Voltage or Full scale Reading
Voltmeter sensitivity is expressed in Ohm/Volt
Rm = Sv × E
Calculation:
Sensitivity of voltmeter = 500 Ω/V
Internal resistance of voltmeter = 500 × 20 = 10 kΩ
Effective resistance across A – B is
= 10 || 15 = 6 kΩ
The voltmeter reading is 10 V
⇒ VAB = 10 V
By voltage division,
Vs = 60 V
