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. Errorneous standardisation. Stray thermal emfs. Stray magnetic fields. Ripples of the DC supply. Errorneous standardisation. Stray thermal emfs. Stray magnetic fields. ANSWER DOWNLOAD EXAMIANS APP
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 ± 8% ± 5% ± 7% ± 6% ± 8% ± 5% ± 7% ± 6% ANSWER DOWNLOAD EXAMIANS APP
