Explain Faraday’s law of electromagnetic induction. If the magnetic flux Φ through a coil changes from 5Wb to 3Wb in 0.1 calculate the induced EMF.
Using Biot-Savart’s law, derive the expression for the magnetic field at the center of a circular current-carrying loop of radius r and current I
Derive Ohm’s law using the concept of drift velocity. Also, explain how resistivity of a conductor depends on temperature.
Calculate the equivalent capacitance of a system where three capacitors, each of capacitance C, are connected in series and then in parallel. What is the ratio of these equivalent capacitances?
Derive the expression for the electric field E due to a uniformly charged thin spherical shell at a point (a) outside the shell and (b) inside the shell.
