MGVCL Exam Paper (30-07-2021 Shift 1) By inserting a plate of dielectric material between the plates of a parallel plate capacitor at constant potential, the energy stored in the capacitor is increased five times. The dielectric constant of the material is 5 1/25 25 1/5 5 1/25 25 1/5 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Energy stored by capacitor, Q = ½CV²Dielectric constant is directly proportional to C and capacitance is proportional to the dielectrical constant
MGVCL Exam Paper (30-07-2021 Shift 1) The operating time of an inverse definite minimum time (IDMT) overcurrent relay corresponding to plug-setting multiplier (PSM) = 1 and time-multiplier setting (TMS) = 1 will be zero 1 sec infinite 3 sec zero 1 sec infinite 3 sec ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Equation of operating time for IDMT relay (t) = 0.14*TMS/[(PSM^0.02) - 1]Here,PSM = TMS = 1So,t = 0.14*1/(1 - 1)t = infinite
