Only for self-evaluation QUESTION 1 A series RL-circuit consist of a 21.6Q resistor and a 74mH inductor. The radial velocity in the circuit is 377rad/s and the supply voltage is represented by the equation: e(t) = 220+ 150 sinut + 120 sin(at+3 + 80 sin ( Sut volt 1.1 Determine an equation for the instantaneous current in the circuit 1.2 Calculate the active power dissipated in the resistor 1.3 Calculate the over-all power factor of the circuit.
