Short Answer TypeA parallel plate capacitor is being charged by a time varying current. Explain briefly how Ampere’s circuital law is generalized to incorporate the effect due to the displacement current.
Net capacitance of three identical capacitors in series is 1 
F. What will be their net capacitance if connected in parallel?
In the meter bridge experiment, balance point was observed at J with AJ = l.
(i) The values of R and X were doubled and then interchanged. What would be the new position of balance point?
(ii) If the galvanometer and battery are interchanged at the balance position, how will the balance point get affected?
Draw a labelled diagram of a full wave rectifier circuit. State its working principle. Show the input-output waveforms.
Two heating elements of resistance R1 and R2 when operated at a constant supply of voltage, V, consume powers P1 and P2 respectively. Deduce the expressions for the power of their combination when they are, in turn, connected in (i) series and (ii) parallel across the same voltage supply.
What happens to the width of depletion layer of a p-n junction when it is (i) forward biased, (ii) reverse biased?
What is sky wave communication? Why is this mode of propagation restricted to the frequencies only up to few MHz?
Using the curve for the binding energy per nucleon as a function of mass number A, state clearly how the release in energy in the processes of nuclear fission and nuclear fusion can be explained.
The binding energy per nucleon increases when a heavy nucleus breaks into two lighter nuclei. That is, energy would be released during the process of nuclear fusion.
When light nuclei join to form a heavy nucleus, the binding energy per nucleon of fused heavier nucleus is more than the binding energy per nucleon of lighter nuclei. Again, there is release of energy in this process
