3) Find the valve of V using the Thevenin Equivalent Circuit and then determine if the 8 ohm resistor allows maximum power transfer. If not, then what value should the 8 ohm resist or be changed to for maximum power transfer? ZA 360 Am 6t + 22V V 3402 22 62 Mw m

Find the valve of the voltage Vx using the THEVENIN 2) equivalent circuit and redo the problem with the NORTON equivalent circuit. Show both the flavinen and Norton Circuits DAY ww 1 23 www + 4444 5 63

Figure  shows the block diagram of a feedback control system with a disturbance signal N(s). Obtain the output Y(s) due to both R(s) and N(s).

A 3-phase, 6-pole induction motor is con- nected to a 60 Hz supply. The voltage in- duced in the rotor bars is 4 V when the ro- tor is locked. If the motor turns in the same direction as the flux, calculate the approxi- mate voltage induced and its frequency: a. At 300 r/min b. At 1000 r/min c. At 1500 r/min

Make a drawing of the magnetic field cre- ated by a 3-phase, 12-pole induction motor. How can we change the direction of rota- tion of a 3-phase induction motor?
