Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It uses centre zero galvanometer instead of voltmeter. It does not load the circuit at all. It loads the circuit to maximum extent. It loads the circuit moderately. It uses centre zero galvanometer instead of voltmeter. It does not load the circuit at all. It loads the circuit to maximum extent. It loads the circuit moderately. 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 Stray thermal emfs. Stray magnetic fields. Ripples of the DC supply. Errorneous standardisation. Stray thermal emfs. Stray magnetic fields. Ripples of the DC supply. Errorneous standardisation. ANSWER DOWNLOAD EXAMIANS APP
