2.2.5.1 A voltmeter with an internal resistance of 10MQ is used to measure the voltage vab in thecircuit below. What is the measured voltage? What voltage measurement would you expect from anideal voltmeter?5M2a12V10M26V and OV since no current6V, 8V4V, 5V6V, 6V the same!

Given ,V=12 voltR1=5 MΩRab=10 MΩUsing voltage divider rule at Rab, Vab=12 Volt×10 MΩ10 MΩ+5 MΩ= 8 volt For voltmeter with 10 MΩ resistanceAs we can observe from above figure , 10 MΩ II 10 MΩWhen two resitances are in parallel, Rab=10 MΩ×10 MΩ10 MΩ+10 MΩ=5 MΩin that case, Rab=5 MΩthen, Vab=12 V×5 MΩ5 MΩ+5 MΩ=6 VoltAnswer : Measured voltage, ideal voltmeter voltage is 6V, 8V respectivelyHence, Option B is correct.
