### Section A

Section A

(Timing: Wednesday and Thursday, 10:00 AM – 12:00 PM)

- To Study the variation of power transfer by two different loads by a DC source and to verify maximum power transfer theorem.
- To study the variation of charge and current in a RC circuit with a different time constant (using a DC source).
- To study the behavior of a RC circuit with varying resistance and capacitance using AC mains as a power source and also to determine the impedance and phase relations.
- To study the voltage and current behavior of an LR circuit with an AC power source. Also determine power factor, impedance and phase relations.
- To study the characteristics of a semi-conductor junction diode and determine forward and reverse resistances.
- To study the magnetic field along the axis of a current carrying circular coil. Plot the necessary graph and hence find radius of the circular coil.
- To determine the specific resistance of a material and determine difference between two small resistance using Carey Fosters Bridge.
- To convert a galvanometer into an ammeter of a given range.
- To convert a galvanometer into a voltmeter of a given range.

- To study the damping with electromagnetic force using compound pendulum (coil and different resistances).
- To determine Young modulus by bending of beam.
- To determine Y, σ and η by Searle's method.
- To study the specific-rotation of sugar solution by polarimeter.
