Question 3: Short Answer Question

Two bulbs are rated (P1, V) and (P2, V). If they are connected

1. in series and
2. in parallel across a supply V, find the power dissipated in the two combinations in terms of P1 and P2.

Question 4: Long Answer Question

1. Identify the part of the electromagnetic spectrum used in
   (i) radar and
   (ii) eye surgery.
   Write their frequency range.
2. Prove that the average energy density of the oscillating electric field is equal to that of the oscillating magnetic field.

Question 5: Very-Long Question

1. In a series LCR circuit connected across an AC source of variable frequency, obtain the expression for its impedance and draw a plot showing its variation with frequency of the AC source.
2. What is the phase difference between the voltages across the inductor and the capacitor at resonance in the LCR circuit?
3. When an inductor is connected to 200 V dc voltage, a current of 1 A flows through it. When the same inductor is connected to a 200 V, 50 Hz AC source, only 0.5 A current flows. Explain why? Also, calculate the self-inductance of the inductor.
