SSC JE Electrical 2019 with solution SET-1 When the only current source is active in the circuit, find the current through the 10Ω resistor 0.66 A 1.33 A 0 A 1.66 A 0.66 A 1.33 A 0 A 1.66 A ANSWER DOWNLOAD EXAMIANS APP
SSC JE Electrical 2019 with solution SET-1 What would the total loss of the 2kVA transformer corresponding to maximum efficiency be, provided the transformer has the iron of 150 W and full-load copper loss of 250W? 400 W 500 W 300 W 100 W 400 W 500 W 300 W 100 W ANSWER EXPLANATION DOWNLOAD EXAMIANS APP When variable loss becomes equal to the constant loss, efficiency is maximum.Losses = Pi + PcSince copper loss is a variable loss thereforeLosses = Pi + Pi = 2piThus at a maximum efficiency of this transformer total loss= 150 x 2 = 300 W
SSC JE Electrical 2019 with solution SET-1 Find the net capacitance of the combination in which ten capacitors of 10 μF are connected in parallel 50 μF 100 μF 1 μF 0.1 μF 50 μF 100 μF 1 μF 0.1 μF ANSWER EXPLANATION DOWNLOAD EXAMIANS APP When the capacitance is connected in series the total capacitance is given byCeq = C1 + C2 + C3………CNCeq = 10nCeq =10 × 10 = 100 μF
SSC JE Electrical 2019 with solution SET-1 If an alternator is operating at unity power factor, then its terminal voltage is Greater than the induced EMF, with negative voltage regulation Less than the induced EMF, with negative regulation Equal to the induced EMF, with zero voltage regulation Less than the induced EMF, with positive voltage regulation Greater than the induced EMF, with negative voltage regulation Less than the induced EMF, with negative regulation Equal to the induced EMF, with zero voltage regulation Less than the induced EMF, with positive voltage regulation ANSWER DOWNLOAD EXAMIANS APP
SSC JE Electrical 2019 with solution SET-1 The annual load factor of a generation station is equal to (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per year) ⁄ (Max. possible demand × 8760) (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per month) ⁄ (Max. possible demand × 8760) (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per year) ⁄ (Max. possible demand × 8760) (No. of units actually supplied per year) ⁄ (Max. possible demand) (No. of units actually supplied per month) ⁄ (Max. possible demand × 8760) ANSWER DOWNLOAD EXAMIANS APP
