This PhysCast is going to look at the magnetic force on a moving charge.

This PhysCast will be analysing a complicated multi-loop circuit.

This PhysCast will look at a problem using a circuit containing a resistor and an inductor in series with a voltage source - an RL circuit.

An object is placed 15 cm before a convex lens with focal length 5 cm. A concave lens of focal length 10 cm is placed after the first lens with 20 cm separation between them. Make a ray diagram and confirm your answers by numberical calculations.

A uniformly charged insulating sphere of radius a and net charge -2Q is placed inside the cavity of a conducting shell of an inner radius b and other radius c. If the shell has a net charge of 3Q and is concentric to the sphere, find the electric field in different regions (a) Rb (d)bc.

This PhysCast is going to look at the resistivity of a piece of material and how to calculate the resistance of a particular arrangement.

This PhysCast is will use Ohm's Law to look at the properties of a small electric motor.
