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. Both X and Y are equally sensitive. X is more sensitive. Y is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. Both X and Y are equally sensitive. X is more sensitive. Y is more sensitive. ANSWER DOWNLOAD EXAMIANS APP
