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 = 250V and V2 = 250V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. V1 = 200V and V2 = 300V. V1 = 250V and V2 = 250V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. V1 = 200V and V2 = 300V. ANSWER DOWNLOAD EXAMIANS APP

Measurement and Instrumentation In DC potentiometer measurments, a second reading is often taken after reversing the polarities of the DC supply and the unknown voltage and the average of the two reading is taken. This is with a view of eliminate the effects of Ripples of the DC supply. Stray magnetic fields. Errorneous standardisation. Stray thermal emfs. Ripples of the DC supply. Stray magnetic fields. Errorneous standardisation. Stray thermal emfs. 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% ± 1.4% ± 2.4% ± 3.4% ± 1% ± 1.4% ± 2.4% ± 3.4% ANSWER DOWNLOAD EXAMIANS APP
