Given that,
Voltage range = 50 V
Sensitivity = 40 KΩ/V
Total resistance = Sensitivity × Voltage range
= 40 KΩ/V × 50 V
= 2000 KΩ
= 2 MΩ
Voltage range = 50 V
Sensitivity = 40 KΩ/V
Total resistance = Sensitivity × Voltage range
= 40 KΩ/V × 50 V
= 2000 KΩ
= 2 MΩ

Ω/V. What is the internal resistance of the voltmeter?
Using the formula:
V = IR
where V is the voltage measured by the voltmeter, I is the current passing through the voltmeter, and R is the internal resistance of the voltmeter.
For a 50 V range voltmeter, the maximum voltage that can be measured is 50 V. The sensitivity of the voltmeter is 40 KΩ/V, which means that for every 1 V measured, the current passing through the voltmeter is 1/40 KΩ or 25 μA.
To measure the full range of 50 V, the current passing through the voltmeter would be:
I = V/R
25 μA = 50 V/R
R = 50 V/25 μA
R = 2 KΩ
Therefore, the internal resistance of the voltmeter is 2 KΩ.
