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

Measurement and Instrumentation
The time/div and voltage axes of an oscilloscope have been creased. A student connects a 1 KHz, 5 V P-P square wave calibrition pulse to channel-1 of the scope and observes the screen to be as shown in the upper trace of figure. An unknown signal is connected to channel-2 (lower trace) of the scope. If the time/div and V/div on both channels are the same, the amplitude (P-P) and period of the unknown signal are respectively

 5 V, 2 ms.
  7.5 V, 2 ms.
 10 V, 1 ms.
 5 V, 1 ms.
