Did you know?
WebVoltmeter A has a sensitivity of 1000 Ω/V while Voltmeter B has a sensitivity of 20,000 Ω/V. The operating range of both voltmeters is in between 0-50 V. By theory, the voltage drop across 50 KΩ resistor is given by Voltage Divider Rule Vr1 = [R1/(R1+R2)]VTotal V50KΩ = [50/(50+100)]150 = 50 Volt We will call this value as True Value.
