2  Electricity & Magnetism

Topics covered at this level. . .

BASIC ELECTRICITY: current, voltage, resistance, power =VI, energy =VIt. Ohm's law V=IR, ohmic resistors,                                 series & parallel resistors. Component characteristics and uses (includes diodes)


ELECTRIC FIELDS: electrostatics,    electric field strength,     force on a charge,     Ep (electrical),


MAGNETISM: magnetic fields,      magnetic force on a current (F=BIL), right hand rules,                                      magnetic force on a charge (F=Bqv),     electric motor.


INDUCTION: wire moving in a magnetic. field,   V = BvL,      Applications – production of electricity, simple generator, [transformer, induction coil – level 3]
