Electricity make things work.  It makes lights glow, it makes electric motors spin, and it makes doorbells buzz.  Electricity is a type of energy.  Battery contains special materials.  These materials containing energy.  When a battery is connected to a machine, the energy in the materials is turned into electricity.  Electricity can only flow around the complete loop, the loop is called an electric circuit.  Electricity is not flow around the circuit on its own, it needs a push.  That is the job of the battery.

All batteries have two places where they join, or connect to an electric circuit.  These places are called terminals.  One is labelled with a + and the other one is labelled with a -.  These labels mean plus and minus.  All devices such as remote controls, clocks, and smoke detectors clearly show the plus and minus labels.

Electricity flows out of the plus terminal.  And it flows back in at the mine’s terminal.  When you put a battery into a machine the battery should face the right way.  Otherwise the machine won’t work.  Hence it is important to get your batteries in the right position.  Batteries come in all sorts of shapes and sizes.  There are batteries smalls P that power things such as watches and hearing aids, and there are also batteries, beer and heavier than bricks.

Large batteries normally have more energy in them than smaller batteries.  A large battery will lighted torch bulb for longer than a smaller battery.  We often use batteries together to give electricity bigger push.  All batteries slowly run out of electricity as we use them.  When they have completely run out they cannot push electricity any more.  When Senna batteries run out, you cannot use them again.  When some batteries run out we can refill them with electricity.  These batteries are called rechargeable batteries.  Filling them up with electricity is called recharging, and they can be recharged hundreds of times.

Mobile phones, music players and laptop computers or get their electricity from batteries.  This means we can take them where we like.  Many electric power tools such as drills saws and screwdrivers get their electricity from batteries.  These tools are known as cordless tools because they have no power cord.

Powerful electricity is dangerous.  It can give you an electric shock and it could hurt you very badly.  That is why it is important to get a qualified electrician to work on all your electrical devices such as Ballarat electrician.  Even a car battery can give you an electric shock and some of the materials inside batteries are harmful, so you should never open up a battery as they may contain acid.

You should always take all batteries to your local recycling centre and then the materials inside can be recycled.
