IGCSE Physics 2 Electricity
This course covers mains electricity, energy and potential difference in circuits, and electric charge.
Mains electricity covers hazards of electricity, insulation, fuses and circuit breakers, electrical transfer of energy and an increase in temperature, power, energy transferred, alternating current and direct current.
Energy and potential difference in circuits covers series and parallel circuits, wires, resistors, metal filament lamps and diodes, resistance and current in a circuit, ldrs and thermistors, lamps and leds, voltage = current x resistance, charge = current x time, electric current and electrons, and energy transferred per unit charge passed.
Electric charge covers common materials which are electrical conductors or insulators, charging by friction, forces between charges, movement of electrons, potential dangers of electrostatic charges, and uses of electrostatic charges.
(NOTE: Whilst this course is based on the Edexcel IGCSE syllabus, the bulk of its content is applicable to other IGCSE and GCSE curricula. It is a useful course for anyone who needs some additional input, delivered in a different way and with some questions to try!)
