Find inverse Laplace transform of following:
1.F(s)=(S+1) / ((S+2)^2 (S+2S+4)^2 )
A 50 Hz, 885 V/88.5 V transformer is used for stepping down voltage. Its HV winding resistance and reactance are 90 ohms and 85 ohms respectively and its LV winding resistance and reactance are 9 ohms and 8.5 ohms respectively. Its core-loss as measured from the primary side = 6 W. The load connected to it = 6 + j7 ohms.
What is the value of its core-loss resistance in k.ohms when looked from the primary side?
What is its core-loss in W when looked from the secondary side?
What is the magnitude of the current that flows through the given load in A?
What is the power consumed in the load in W?
What is the magnitude of the current that will be flowing into the primary winding in A if the excitation current is neglected?
A 205 V, 19 kW dc shunt motor has a 3 step (3 resistance) starter that restricts the starting armature current between its rated value and some K times this rated value. This motor is 69 % efficient at rated conditions and its field resistance = 205 ohms. The starting resistance in each step is 6 times its armature resistance.
What is the maximum starting armature current in A?
What is total resistance of the starter in Ohms?
What is the back EMF in Volts, when the starter is just put in 2nd step? Assume that the transition from 1st to 2nd step is instantaneous.
What is the back EMF in Volts by the end of the 2nd step?
What is the back EMF of this motor in Volts under rated conditions?
