ETEE 1223 Homework 14 Hints I. Remember each coil involves 2 terms, one from the self inductance and one from the mutual inductance. You need to watch those dots pretty carefully to get the correct sign on the mutual inductance term. Remember the mutual term is the voltage on your coil caused by the current in the OTHER coil. Answers: I2= 4.398 angle -40.43 P = 386.8 W II. This one is tricky because in loop 2 you have both coils. You will have to be VERY careful in order to get the loop equation written down correctly. There are 2 terms for each coil plus a term for the 444 ohm resistor, giving a total of 5 terms. Answers: a. M=0.272 H b. j80, j320 and j136 ohms. Put these on your circuit diagram to do part c. c. I2 = 14.25 angle 20. (If you get this right, you can be proud of your ability to handle mutual inductance problems!)
