If the negatively charged balloon is brought close to the positively charged cloth, it attracts the wool. If two negatively charged balloons are brought close together, the like charges repel and the balloons move away from each other. Current is the rate of flow of electrons. Unlike static electricity, current electricity must flow through a conducter, usually copper wire. Household current is usually no more than 30 amps.
Current electricity is a stream of electron s flowing through a conductor.
There are different sources of current electricity including the chemical reactions taking place in a battery and the application of pressure on quartz crystals. However, the most significant source is the generator. A simple magneto, or generator, produces electricity when a coil of copper turns inside a magnetic field. In a power plant, electromagnets spinning inside an armature of many coils of copper wire generate vast quantities of current electricity. The electrons are set in motion by a chemical reaction in a battery and flow only one way.
