Electronic Measurements And Instrumentation

  1. Two voltmeters one with a full scale reading of 100 V and another with a full scale reading of 200 V, are connected in series across a 100 V supply. The internal resistance of both meters is the same. What are the readings?
    1. 100 V and 0 V
    2. 75 V and 25 V
    3. 67 V and 33 V
    4. 50 V and 50 V
Correct Option: D

The given problem can be better understand by the figure given below:
Since both the voltmeter have same internal resistance and the voltmeter are connected in series across a 100V supply. Hence the reading of both the voltmeters will be same i.e. 50V.
