After taking this module students should be able to:
- Calculate the force on a charged particle in electric and magnetic fields.
- Describe the motion of a charged particle in a uniform electric field.
- Calculate the potential of a system of charged particles.
- Describe the structure and function of resistors, and capacitors.
- Carry out calculations on capacitors involving stored energy, charging and discharging.
- Calculate internal resistance, energy and power in DC circuits.
- Calculate DC currents and voltages in resistor networks using Kirchoff's rules.
- Calculate reactance and impedance in AC circuits.
- Use phasor diagrams, vector methods and complex numbers to analyse AC circuits.
- Apply conditions or resonance in RCL circuits.
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 alternative approach of Gauss's Law is introduced. 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.
