1-1 Electric charges 12-13 Atoms are made of normally even smaller particles. Three particles are however protons, neutrons, also electrons. When charged particles come near one another they give
rise to two different forces. A force of repulsion exists between particles of the same charge. A force of attraction exists between oppositely charged particles. 1-2 static electricity 17 Certain
materials permit electric charges to flow freely. Most materials are good conductors of electricity, for example, silver, copper, aluminum, and mercury are among the best conductors.



1-3 The flow of electricity 22-25 A continuing flow of electric charges is produced by a device that changes another form of energy into electrical energy. A device that converts other forms of
energy into electrical energy is known as a source of energy. The difference between a wet cell and a dry cell, for example, is that in a wet cell thieres liquid, and a dry cell has a paste such as
a mixture. A battery is made of several smaller units called electrical cells, or electrochemical cells. When a wire is connected to the terminals of a source, a complete path called a circuit is
formed. A flow of charge is called an electric current. Therefore the higher the electric current in the wire, therefore, the faster.



1-4 Electric Circuits 31-32 An electric circuit consists of a source of energy a load, or resistance wires and a switch. The load is the device that uses the electric energy. The load can be a
light bulb, an appliance a machine or a motor. In all cases, the load offers some resistance to the flow of electrons. As a result, electric energy is converted into heat, light, or mechanical
energy. If all the parts of an electric circuit are otherwise called one after another, the circuit is a series circuit. In a series circuit, there is only one path for the electrons to flow. The
disadvantage of a series circuit, the entire circuit is opened and no current can flow. In a parallel circuit, the different parts of an electric current are on separate branches.
