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. Stray thermal emfs. Errorneous standardisation. Ripples of the DC supply. Stray magnetic fields. Stray thermal emfs. Errorneous standardisation. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation Assertion (A) : It is always desirable to take the reading of an indicating instrument very close to the full scale reading. Reason (R) : Accuracy of an indicating instrument is maximum at the full scale deflection and error increases as reading comes closer to the beginning of the scale. A is true but R is false Both A and R are true but R is NOT the correct explanation of A A is false bur R is true Both A and R are true and R is the correct explanation of A A is true but R is false Both A and R are true but R is NOT the correct explanation of A A is false bur R is true Both A and R are true and R is the correct explanation of A ANSWER DOWNLOAD EXAMIANS APP
