Measurement and Instrumentation The total current I = I1 + I2 in a circuit is measured as I1 = 150 ± 1A , I2 = 250 ± 2A, where the limits of error are as standard deviations. I is measured as (400 ± 1) A (400 ± 1.5) A (400 ± 3) A (400 ± 2.24) A (400 ± 1) A (400 ± 1.5) A (400 ± 3) A (400 ± 2.24) A ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation A slide wire potentiometer has 10 wires of 1 m each. With the help of a standard voltage source of 1.018 V it is standardised by keeping the jockey at 101.8 cm. If the resistance of the potentiometer wires is 1000 ohm, then the value of the working current will be 100 mA. 1mA. 0.5 mA. 10 mA. 100 mA. 1mA. 0.5 mA. 10 mA. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation If two meters X and Y require 40 mA and 50 mA respectively, to give full scale deflection, then It would not be possible to assess the sensitivity on the basis of the given data. Y is more sensitive. Both X and Y are equally sensitive. X is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. Y is more sensitive. Both X and Y are equally sensitive. X is more sensitive. ANSWER DOWNLOAD EXAMIANS APP
