Give reason for your answer. Electrostatic Potential and Capacitance A 12 pF capacitor is connected to a 50 v battery.

How much electrostatic energy is stored in the capacitor? If another capacitor of 6 pf is connected in series with it with the same battery connected across the combination, find the charge stored and potential difference across each capacitor.

Depict the equipotential surfaces due to an electric dipole. Current Electricity Derive an expression for drift velocity of electrons in a conductor. A wire whose cross sectional area is increasing linearly from its one end to the other, is connected across a battery of V volts.

Which of the following quantities remain constant in the wire? Justify your answer.

Explain briefly how these rules are justified. The current is drawn from a cell of emf E and internal resistance r connected to the network of resistors each of resistance r as shown in the figure.

Obtain the expression for i the current draw from the cell and ii the power consumed in the network. The potentiometer wire, AB, has a total resistance of R0. A voltage V is supplied to the potentiometer. Derive an expression for the voltage across R when the sliding contact is in the middle of potentiometer wire.

Moving Charges and Magnetism Describe the working principle of a moving coil galvanometer. Why is it necessary to use i a radial magnetic field and ii a cylindrical soft iron core in a galvanometer?

Write the expression for current sensitivity of the galvanometer.

Can a galvanometer as such be used for measuring the current? Show that it behaves like a tiny magnetic dipole. Give the significance of negative sign. Electromagnetic Induction A long straight current carrying wire passed normally through the centre of circular loop.

If the current through the wire increases, will there be an increase induced emf in the loop? Obtain the expression for the mutual inductance of two long co-axial solenoids S1 and S2 wound one over the other, each of length L and radii r1 and r2 and n1 and n2 number of terns per unit length, when a current I is set up in the outer solenoid S2.

Derive the expression for the instantaneous value of the emf induced in the coil. A circular coil of cross-sectional area sq. Calculate the maximum value of the current in the coil. Alternating Current Draw a labelled diagram of a step-up transformer.

Obtain the ratio of secondary to primary voltage in terms of number of turns and currents in the two coils. A power transmission line feeds input power at V to a step-down transformer with its primary windings having turns.

Find the number of turns in the secondary to get the power output at V. Which one leads in phase: Without making any other change, find the value of the additional capacitor C1, to be connected in parallel with the capacitor C, in order to make the power factor of the circuit unity.

Find the intensity of the light transmitted by P2. It deals with bulk systems and does not include the molecular constitution of any matter. It also discusses the difference between the extrinsic semiconductor and intrinsic semiconductor, semiconductor diode, the application of junction diode as a rectifier, etc. Due to these reasons physics has intimate relationship with all the sciences and hence it is called a fundamental science.
