There are three core components, each functions as follows: 1. power supply voltage and current supply is provided with a device that uses electrical power, electrical supply can be taken from various origin, such as from a chemical reaction from the coil cutting the magnetic field, and from the lighting, etc. A unit of measure of volts told (Volt) or V 2. load or electrical device is any device that uses electricity to work. The load is acting power, and other formats such as audio, light, heat, cold and vibration, etc. The load is a term discussed by including all types of electrical equipment such as a fan, what a washing machine, fridge, tv, radio and air conditioning etc. Each type of load to use electric power. Which is represented by a voltage and current power? 3. extension cord-circuit is the conductor, or electrical wiring. Use to connect to the circuit, up to the anniversary. Make the supply voltage of the load caused the stream to flow through the circuit. Supply does not load and back again supply anniversary. Electrical cables, jumpers made with insulated copper to maximize safety in use. 2. per circuit. An important part of an electrical circuit is to load applications. Loads taken per use in electrical circuits can be connected into 3: Series circuit. , A parallel circuit and mixed circuits.2.1 connection the series circuit Cyclic serial meant to bring the electrical devices connected together in a way that one end of the device is plugged into the device 1, 2, and then bring the remaining ends of the device connected to the 2 to 3 and will continue this manner in which this connection will cause an electric current flowing in one direction of electricity within the circuit will have the same serial every point total resistance of the circuit is to bring the serial resistance all be combined voltage in circuit serial then pressure appears across the resistor has electricity flowing through which.The voltage that occurs is not the same can be calculated from Ohm's law.
