The resistor is a passive electrical Resistors: component that creates resistance in the = flow of electric current. Color codes: Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating Capacitors: device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other. Inductors: It's a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. Voltage divider: (also known as a potential divider) is a passive linear circuit that produces an output voltage (V ou) that is a fraction of its input voltage (Vin). Star connection: connection used in a_ polyphase electrical device or system of devices in which the windings each have one end connected to a common junction, and the other end to a separate terminal. Delta connection: a mesh connection for connecting electrical apparatus to a three-phase circuit. Diodes (PN and NP): PN Junctions are the core components of diodes. In the simplest form, diode blocks current in one direction while passing current in the other direction. Transistors (PNP and NPN): NPN and PNP refer to the arrangement of the pieces that make up the transistor Integrated circuits: An integrated circuit (also called an IC or just a chip) is an entire electronic circuit consisting of multiple individual components such as transistors, diodes, resistors, capacitors, and the conductive pathways that connect all the components, all made from a single piece of silicon crystal. 4- Band Code 1.0 KQ 15% 4th Color _| 1st Band| 2nd Band| 3rd Band Decimal Multiplier|Tolerance Gray | 8 8 8 100,000,000 White 9 9 9 1,000,000,000 Silver 0.01) + 10% None t+ 20% —_ an see 2549 +1% 5- Band Code Calculation Loft Right ' =a - 200 Ka + 10% First Band Red --- Second Band Black - Multiplier Band Yellow -- x10,000 The Gold or Silver band is always placed to the right.
