### Learning Outcomes

On successful completion of this module students should be able to:

1. Calculate the force on a charged particle in electric and magnetic fields with the particle stationary or in motion.
2. Calculate the electric field of a system of charged particles.
3. Calculate the potential of a system of charged particles.
4. Be able to use the right hand rules to determine the induced current for a simple system.
5. Carry out calculations for simple DC circuits involving capacitors, resistors, inductors and batteries using Kirchhoff's rules and other methods.
6. Carry out calculations for simple AC circuits.

### Brief description

The concept of electric charge is introduced and electric force, field and potential are explained in terms of Coulomb's Law with illustrative examples. The flow of charge is considered and this leads to Ohm's Law and the concept of resistance. Capacitors and resistors are examined and examples are given of their use in electric circuits. A brief introduction to magnetism is given
