Measurement and Instrumentation
If two 300V full scale voltmeters V1 and V2 having sensitivities of 100 kOhm/V and 150 kOhm/V are connected in series to measure 500V then

 V1 = 200V and V2 = 300V.
 V1 = 250V and V2 = 250V.
 V1 = 300V and V2 = 200V.
 V1 = 0V and V2 = 0V.

Measurement and Instrumentation
Assertion (A) : It is always desirable to take the reading of an indicating instrument very close to the full scale reading. Reason (R) : Accuracy of an indicating instrument is maximum at the full scale deflection and error increases as reading comes closer to the beginning of the scale.

 Both A and R are true and R is the correct explanation of A
 A is true but R is false
 Both A and R are true but R is NOT the correct explanation of A
 A is false bur R is true
