JEE Advanced Physics Syllabus can be referred by the IIT aspirants to get a detailed list of all topics that are important in cracking the entrance examination. JEE Advanced syllabus for Physics has been designed in such a way that it offers very practical and application-based learning to further make it easier for students to understand every concept or topic by correlating it with day-to-day experiences. In comparison to the other two subjects, the syllabus of JEE Advanced for physics is developed in such a way so as to test the deep understanding and application of concepts.

**Q1. An inductive coil has a resistance of 100 Î©. When an ac signal of frequency 1000 Hz is fed to the coil, the applied voltage leads the current by 45°. What is the inductance of the coil?**

**Q2. Fig shows a source of alternating voltage connected to a capacitor and a resistor. Which of the following phasor diagrams correctly describes the phase relationship between I**

_{C}, the current between the source and the capacitor, and I_{R}, the current in the resistor?
Solution

(a)
Since the capacitor is connected in series to the resistor, current I

_{C}from the supply and I_{R}through the resistor is in phase as represented by choice (a)

**Q4. The value of current in two series LCR circuits at resonance is the same. Then**

Solution

X_L/X_C =1 for both circuits

Impedance may be different if the applied voltage is different

**(c)**X_L=X_C at resonanceX_L/X_C =1 for both circuits

Impedance may be different if the applied voltage is different

**Q5. AnLCR circuit contains resistance of 100 Î© and a supply of 200 V at 300 rad angular frequency. If the only capacitance is taken out from the circuit and the rest of the circuit is joined, current lags behind the voltage by 60°. If, on the other hand, only the inductor is taken out the current leads by 60° with the applied voltage. The current flowing in the circuit is**

Solution

**(b)**At resonance, the series combination of L and C gives zero impedance. At resonance, the voltage across L and C are equal but opposite in phase**Q8. A capacitor of capacitance 1 Î¼F is charged to a potential of 1V. It is connected in parallel to an inductor of inductance 10**
