Electric Circuits and Light Energy
Electricity is the movement of charged atomic particles called an electron. Moving electron create the power of a lightning strike. They also light up your room when you flip the switch.
A battery is a chemical device designed to create the force need to move electrons. Conductors provide a path for the electrons to flow on. Electrons have a negative charge. They travel out of the minus end of the battery and are attracted to the plus end. Touch a metal conductor to each end of a battery and electrons begin to flow from minus to plus. Flowing electrons are called the current. Current is measured in Amperes. The force moving the electron is voltage and measured in volts.
Never connect a short wire from the minus to plus on any battery. This is called a short circuit. The conductor gets hot and you might burn yourself and the battery quickly loses energy.
The path that the electric current flows in is called a circuit. This circuit has a light bulb in it. To move electricity through the bulb, we complete the circuit by touching the metal wire to each end of the battery. The wire does not get hot because the light bulb reduces the current flowing in this circuit. Electric energy changes to light energy.
Once the circuit is complete, the electric current appears flowing from the minus end of the battery towards the plus end.
Look close at the side of a typical AA battery and you will find a ‘V’ or the word ‘volts’ preceded by a number which is usually 1.5.
Voltage or volts is a measure of the force moving the electrons. It is safe to touch an AA battery because 1.5 V is a low voltage. It is not enough to give you a shock.
High voltage is dangerous. Never experiment with anything that plugs into a wall outlet. Current is another important quantity related to electricity. It is measured in Amperes. It tells us the rate that electrons are flowing at. Ampere is often abbreviated to amp.
