. stable electricity is the accumulation of excess galvanizing charge at the region.
·How Static Electricity is Produced
When two distinct objects that ar insulators (such as a plastic rod and silk cloth) are rubbed together, electrons move from one object to an an different(prenominal).
One object becomes negatively-charged, and the other object becomes positively-charged.
The more rubbing the more electrons are transferred, and the bigger is the charge built up.
Unlike charges (positive and negative) attract each other.
·Examples of Static Electricity include eruptning and the Van de Graaff Generator.
CURRENT ELECTRICITY
·Current Electricity or electric current is the movement of negatively-charged electrons through wires or objects with metals, carbon or water.
·Conductors are substances that allow electrons to travel intimately through them (e.g. metals, carbon and water).
·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 much of the energy 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 acidic or ionic answer (electrolyte solution).
·Different combinations of electrodes beget different voltages. For example, electrodes of zinc and copper produce 1.1 volts, whereas electrodes of aluminium and carbon produce 2.4 volts.
·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 series of connected simple cells.

SERIES CIRCUIT
·Series Circuit - a circuit where the components are connected one after the other into a circle.
