Summarize the following:
Visit your local library or a bookstore to begin reading about electronics. Even older books have a lot of information about electrical circuits and how they work. Use it to study the basics before you begin building your own circuits. Try books like Make: Electronics, The Art Of Electronics, or Foundations of Analog and Digital Electronic Circuits. For more resources, search online for informative websites and digital book copies. Search your phone's Play Store to find a number of informative, hands-on apps. Some apps teach you the basics of electronics, while others let you design your own circuit board using a touchscreen. For example, try Electronics Basics or ElectroDroid. An electrical current consists of electrons, which are the negatively charged particles in atoms. In a current, the electrons flow from a negative source, such as a battery terminal. Then, it flows around the circuit and returns to the positive terminal. You can think of it like a faucet. When the faucet turns on, "water" is pushed through until it reaches the end of the pipe. Voltage is a measurement of the force needed to make a current flow through a circuit. In a circuit, the electrons accumulate near the battery's negative terminal. Energy is needed to get the current to flow through the circuit, and this measurement is the voltage. Think of it as pressure in a water tank. When water is drained from the tank, the pressure goes down and less water flows out. Resistance slows the current in a circuit. Different materials inhibit electricity more than others. You will need a stronger electrical current to pass through insulation than a conductive material like metal. This increases the voltage. For example, imagine water pipes of different sizes. Water faces more resistance flowing through the smaller pipe due to the lack of space. Electrical diagrams and schematics use symbols to denote components. Before you can copy one to build your own circuit, find out what the symbols mean. Search online for a list of symbols used as shorthand in diagrams. The straight lines are wires. A battery is represented by a + sign followed by a long and short straight line. Diodes, for example, are represented by triangles. Resistors are represented by squares or jagged lines.
Read books to learn the fundamentals of electronics. Download a phone application to study electrical engineering. Study how a current travels along a wire. Read about the voltage in a circuit. Study the resistance factor of different objects. Read circuit diagrams to understand the notation.
