Measurement and Instrumentation A variable w is related to three other variables x, y and z as w = xy/z. The variables are measured with meters of accuracy ± 0.5% reading, ± 1% of full scale value and ± 1.5% reading. The actual readings of the three meters are 80, 20 and 50 with 100 being the full scale value for all three. The maximum uncertainty in the measurement of w will be ± 7% ± 6% ± 5% ± 8% ± 7% ± 6% ± 5% ± 8% ANSWER DOWNLOAD EXAMIANS APP

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