- Apply conditions for resonance in RCL 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.
