Physics Igcse Electricity Pdf The document also defines key electrical concepts such as current, voltage, resistance, and ohm's law, and how components behave in series and parallel circuits. Current i is measured in amperes (a) and is the rate of flow of charge at a point in the circuit. the current is given by i=q t, where q is measured in coulombs (c) and t in seconds (s). in metals, current is due to a flow of electrons. in solutions it can be the flow of ions.
6 Igcse Mains Electricity Pdf Electric Power Alternating Current 4.2 electrical quantities 4.2.1 electric charge like charges repel; opposite charges attract conducting sphere is mounted on an insulating stand. explain how you would use a positively charged rod of insulating material to change the sphere by induction (3). When two insulators are rubbed together, electrons move from one to the other and they become charged. for example, when a rod is rubbed with a cloth, electrons are transferred from the rod onto the cloth and the rod becomes positively charged. Allow ideas of “earthing” or “grounding” e.g. “it (charge car) is earthed by the strap”. For your exam, you must explain how insulation, double insulation, earthing, fuses and circuit breakers protect the device or user in diferent domestic appliances. remember that a charge moving around an electrical circuit are an example of an electrical transfer pathway.
