(ii) Active element has ability to deliver power for infinite duration.
(iii) Voltage & current source are active elements.
(iv) Series resonance circuit is called current rejector circuit.
Which of the above statements are correct?
AC current cannot be measured directly by
A 3-ϕVoltage source with line voltage of 120 Vrms is used to drive a balanced delta connected load consisting of 3 impedances each with ZL = (12 + j9) Ω through a set of power lines each of which has an impedance of (1 + j0.5) Ω. The power delivers to the load is ______.
A Balanced abc- sequence, Y-connected source with Van = 100∠10° V is connected to a Δ-connected balanced load of (8 + j4)Ω per phase. Calculate the line ‘a’ current in the load.
Two balanced 3-φ, star connected system are interconnected as shown in figure:
The set of 3 equal resistors, each of value R Ω, are connected in star across R-Y-B as shown in figure & consumes the same power as the unbalanced∆connected load. Find the value of resistor R?
