Assertion A: BJT is not preferable for the circuits with negative half cycle like AC sources.

Reason R: Base emitter junction of Power BJT is heavily doped.

Consider the following statements.

1. Power factor is defined as the ratio of active power to apparent power in an AC circuit.

2. The magnitude of power factor is always less than or equal to unity.

Which of the above statements are correct?

Current flowing through a switch is given below. What will be the RMS current rating of the  switch?

V_S = 10cost and the complex power drawn in P_complex =  the value of R and C respectively.

A 3-phase, 50 Hz, 4-pole alternator with 3 slots/pole/phase has 4 conductor per slot with a double layer winding. The coil span is 6 slots and the flux per pole is 0.1 Wb. The emf per phase (in volts) and distribution factor are_______.

Consider the circuit shown below. If all the flip-flops are initially cleared, then the count (Q₁, Q₂, Q₃) after 114 clock pulses is?

A 3-phase, 50 Hz, 500 km long hollow transmission line has its conductors at the corners of an equilateral triangle with side 3 m. The diameter of each conductor is 2 cm. Find the steady state limit (in MW) ignoring the capacitance of the line? (|V_s| = |V_R| = 200 kV)
