Measurement and Instrumentation If two meters X and Y require 40 mA and 50 mA respectively, to give full scale deflection, then Y is more sensitive. Both X and Y are equally sensitive. X is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. Y is more sensitive. Both X and Y are equally sensitive. X is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. ANSWER DOWNLOAD EXAMIANS APP

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

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 = 300V and V2 = 200V. V1 = 250V and V2 = 250V. V1 = 200V and V2 = 300V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. V1 = 250V and V2 = 250V. V1 = 200V and V2 = 300V. V1 = 0V and V2 = 0V. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation A resistance is measured by the voltmeter-ammeter method employing dc excitation and a voltmeter of very high resistance connected directly across the unknown resistance. If the voltmeter and ammeter reading are subject to maximum possible errors of ± 2.4 % and ± 1.0 % respectively, then the magnitude of the maximum possible percentage error in the value of resistance deduced from the measurement is nearly ± 1.4% ± 3.4% ± 2.4% ± 1% ± 1.4% ± 3.4% ± 2.4% ± 1% ANSWER DOWNLOAD EXAMIANS APP
