After taking this unit the student should be able to:
* state the basic laws of electricity and magnetism;
* define scalar and vector fields and represent them graphically;
* determine the forces due to electric and magnetic fields acting on charges and currents;
* determine electric fields, potentials and energies due to simple, static charge distributions;
* determine magnetic fields and energies due to simple, steady current distributions;
* determine electric fields, e.m.f.s and induced currents due to varying magnetic fields;
* demonstrate the correct use of common laboratory equipment, maintain a scientific logbook, perform basic error analysis and produce a scientific report.
