When a voltage v(t)=250 sin[314t-(pi/4)] is applied to a circuit,the current in the circuit is found to be i(t)=50 sin[314t-(pi/2)] amperes. Find the circuit elements,power & power factor.
What are the techniques used to make feedback system stable? Explain and draw the frequency response of a 1-pole feedback amplifier.
Determine the rotational speed required to generate a sinusoidal voltage of 24V in a 25-turn coil that rotates within two pole field of 0.012 wb/pole.
A 3kw, 120V, 2400 rpm shunt motor has an armature resistance of 0.4 ohms and a shunt field resistance of 160 ohms. The motor operates at full load. The no load current is 2A. If an external resistance of 2.5 ohms is insertions in the armature circ..
