.Basic Electronics:

To get electricity the purpose of electronics is to do useful and interesting things. The concept of electricity based on practical experience is familiar and mysterious.

Electricity flows through wires; it comes from power plants that catch the wind, burn coal, or harness nuclear reactions.
It comes through the walls to get electrical outlets through wires. Electricity is not free. When the batteries die, electricity is gone so we can store them in batteries. It travels to our house in big cables hung high in the air from the power plants.
Batteries are rechargeable, they drain all their electricity, and put it back by plugging them into a charger.
Which transfers electricity into the battery from an electrical outlet.

• Electricity can be measured in volts.
• Electricity can be measured in watts.
• Electricity can be very dangerous.

There are two types of electric charge:

Positive and negative. The positive charge has protons or the negative charge has electrons. Electric current flows from atom to atom. Current atom flows are called conductors and where the atom does not currently flow easily is called insulators. The electrical circuit consists of three elements: a lamp, an electrical, and a battery wire that connects the two. It is made of electrical elements and conductors.
