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.
Figure 2 shows three "LC" circuits, two of them with capacitance capacitors "C" and the three with inductance coils "L", the three circuits are coupled by means of two capacitance capacitors "Cc". The currents that circulate through each mesh are those indicated in the figure: "I1", "I2" and "I3". Using Kirchhoff's law for voltages and taking into account the definition of current I = −dQ / dt, find the system of coupled equations of the system and then find the normal angular frequencies of the system.

In part 1 of this lab you will move a coil from well above to well below a strongpermanent magnet. You will measure the current in the loop during this motion using acurrent sensor. The program will also display the flux “measured” through the loop, eventhough this value is never directly measured. In this problem you will understand how.(a) Starting from Faraday’s Law and Ohm’s law, write an equation relating thecurrent in the loop to the time derivative of the flux through the loop.(b) Now integrate that expression to get the time dependence of the flux through theloop Φ(t) as a function of current I(t). What assumption must the software make (whatvalue must it arbitrarily set) before it can plot flux vs. time?
