Q4(a) Compare and contrast between Electric field and Magnetic field. (b) Explain the Volt-Ampere characteristics of a pn junction diode with an appropriate sketch. (c) The following are the specifications for a given series magnetic circuit: Number of turns, N=400t Area of cross-section, A=2x103 m2 Length, l=16 mm Magnetic Flux, Ø=4x10-4 wb Magnetizing Force, H-170 A.t/m Determine current, permeability of the medium and relative permeability.

Where is electrical energy stored in an inductor? O In the electric field surrounding its coils. O In the magnetic field surrounding its coils. O In both the electric and magnetic field surrounding its coils. O An inductor never stores electrical energy.

Question 3 The number of carriers reaches a maximum at an energy close to the edges of the two bands (Conduction and Valence). Find the expression for the energy where the number of carriers reaches a maximum (in terms of conduction and valence band energies) keeping in consideration non-degeneracy..Full explain this question and text typing work only     We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line  Fast

What causes transients? Select one or more: a. Energy is stored into capacitance and inductance b. Power required for transporting energy can be infinite c. The power required for transporting energy cannot be infinite Od. Energy is stored into resistance and capacitance e. Energy is stored into resistance, capacitance and inductance

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.

The terminal potential difference will be greater than its emf when it is * In open circuit Being charged Being charged or discharged Being discharged
