electric

electric vehicle is required, electricity is something that needs to be on the car, almost all existing systems require electricity.
Electrical equipment has been used in some parts of the car, of course with a variety of functions.
When an electric current flowing through the resistor, this current affects the resistor and can produce some functions.
Electrical equipment utilizing these functions in accordance with its objectives by changing the electrical work.
electrical function
1. Heat generating function
The heat generated by the flow of electricity through a resistor, such as the cigarette lighter, fuse.
2. Light-producing function
Light is produced when electricity flows through a resistor, such as the bulb.
3. The function of the magnetic
Magnetic force generated when electricity flows through a conductor or a coil, like the ignition coil, alternator, injectors.

All material is formed of atoms, which are built from atomic nuclei (nucleus) and electrons. Metal atoms contain free electrons.
Free electrons are electrons that can move freely from the atoms.
Movement of free electrons at the metal atom to generate electricity.
This means that electricity flowing through the electrical circuit is the electron moving in a conductor.
When voltage is paired at both ends of a metal (conductor), electrons move from the negative to the positive pole. The flow is in contrast to the electric current flow.

Three electric elements
Electricity consists of three basic elements:
1. flow
This is the current flow in electrical circuits.
Unit: A (ampere)
2. voltage
This is the force that moves electric current through an electric circuit. The greater the voltage, the greater the current flowing through the circuit.
Unit: V (volts)
3. resistance
This is the opposite of current flow.
Unit: Ω (ohm)
