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. Derive the expression for the electric potential due to an electric dipole at a point on its axial line. Depict the equipotential surfaces due to an electric dipole. 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? 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. A resistance of R draws current from a potentiometer.
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. 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. L, where L is the orbital angular momentum of the electron.
Give the significance of negative sign. What is the value of horizontal component of the Earth’s magnetic field at equator? If the current through the wire increases, will there be an increase induced emf in the loop? Self Inductance’ and write its S.
