Measurement and Instrumentation If two 300V full scale voltmeters V1 and V2 having sensitivities of 100 kOhm/V and 150 kOhm/V are connected in series to measure 500V then V1 = 300V and V2 = 200V. V1 = 250V and V2 = 250V. V1 = 200V and V2 = 300V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. V1 = 250V and V2 = 250V. V1 = 200V and V2 = 300V. V1 = 0V and V2 = 0V. ANSWER DOWNLOAD EXAMIANS APP
