STATIC electricity . stable electricity is the accumulation of free galvanizing charge at the region. ·How Static Electricity is P rod carrelluced When deuce distinct fair games that ar insulators (such as a plastic rod and silk cloth) ar rubbed together, electrons move from one object to an an contrasting(prenominal). One object becomes negatively-charged, and the other object becomes positively-charged. The more rubbing the more electrons atomic number 18 transferred, and the bigger is the charge built up. Unlike charges (positive and negative) attract severally other. ·Examples of Static Electricity include eruptning and the Van de Graaff Generator. CURRENT ELECTRICITY ·Current Electricity or electric current is the exercise of negatively-charged electrons finished wires or objects with metals, carbon or water. ·Conductors are substances that dispense with electrons to travel intimately through them (e.g. metals, carbon and wa ter). ·Insulators or non-conductors are substances that do not allow electrons to travel easily through them (e.g. plastic and wood). ·Resistors are substances that are poor conductors. They convert frequently of the dexterity of abject electrons into light, heat or sound energy in light bulbs and stereos.

THE SIMLE CELL ·A simple cell consists of 2 different conductors (electrodes) partially covered by an acidulous or ionic answer (electrolyte solution). ·Different combinations of electrodes beget different voltages. For example, electrodes of zinc and copper take in 1.1 volts, whereas electro des of aluminium and carbon produce 2.4 volt! s. ·Rechargeable Cells (e.g. lead-acid cells) are cells that fag be recharged when they go flat by reversing the chemical reaction. ·Battery - A battery is a serial publication of connected simple cells. plebeian CIRCUIT DIAGRAM SYMBOLS serial CIRCUIT ·Series Circuit - a circuit where the components are connected one after the other into a circle. ·Ammeter - This artifice is used to measure current in amperes (A).
