A fuel injector of inductance 6 mH and resistance 2 2 requires a minimum current of 3 A before it can open to let the fuel flow. a) How long will it take to reach this current when fed from a 12 V supply? How long would it take to reach the same current, if the supply voltage fell to 9 V? You may use the standard equation for a 1st order system: It = Imax (1 - e

You are a journeyman electrician working in an industrial plant. Your task is to connect an inductor to a 480-V, 60-Hz line. To determine the proper conductor and fuse size for this installation, you need to know the amount of current the inductor will draw from the line. The nameplate on the inductor indicates that it has an inductance of 0.1 H. An ohmmeter reveals that it has a wire resistance of 10 . How much current should this inductor draw when connected to the line?

1) In a certain circuit battery is draining out 5 times more quickly than expected for normal operation what could be the possible cause for this and how did you conclude it. 2) Why AC current is preferred over DC current for high power electrical circuits. 3) Initial current across a capacitor connected across a DC source is huge and initial voltage is zero, explain why this is so. 4) Explain the working of AC generator in your own words. 5) In a Wheatstone bridge circuit a student connects a motor in place of galvanometer and is trying to find unknown resistance using formula when he adjusts variable resistor and observes that motor is no more rotating. Do you agree with his technique or not explain with reasoning. 6) What does a negative value of loop current indicates in Mesh Analysis and Method of Branch Currents, and also comment on if there a way to avoid this negative sign appearing for loop current's value.
