SSC JE Electrical 2019 with solution SET-1 Two inductors of 4H and 6H are connected in series. The equivalent inductance of this combination is 2.4 H 10 H 6 H 4 H 2.4 H 10 H 6 H 4 H ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Total inductance when inductor are connected in seriesL = L1 + L2L = 4 + 6 =10H
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 Less than the induced EMF, with positive voltage regulation Equal to the induced EMF, with zero voltage regulation Greater than the induced EMF, with negative voltage regulation Less than the induced EMF, with negative regulation Less than the induced EMF, with positive voltage regulation Equal to the induced EMF, with zero voltage regulation ANSWER DOWNLOAD EXAMIANS APP
SSC JE Electrical 2019 with solution SET-1 In the two wattmeter method, the readings of the two wattmeters are 500W, 500W respectively. The load power factor in a balanced 3-phase 3-wire circuit is: 0.5 1 0.9 0.8 0.5 1 0.9 0.8 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP In two wattmeter method the phase angle is tanφ = √3(W1 − W2)/(W1 + W2) tanφ = √3(500 − 500)/(500 + 500) tanφ = 0° φ = tan−10° = 0° Power factor = cosφ PF = cos0° = 1
SSC JE Electrical 2019 with solution SET-1 In the circuit shown, if R = 0, then the phase angle between v(t) and i(t) is 0° 90° 60° 30° 0° 90° 60° 30° ANSWER EXPLANATION DOWNLOAD EXAMIANS APP In the given circuit if R = 0 then the circuit becomes purely inductive. So the phase angle between v(t) and i(t) is 90°.
