Resistor colour codes Resistor values are encoded as colour codes . Here we are talking about 3 band resistor col0ur coding system and how to remember it easily . The colour coding system is as below The number starts from 0 and ends at 9 . Lets take the first letter of each colour B [...]
Presently we have a variety of cells or batteries to choose from; lead acid, zinc carbon, Nickel cadmium and Nickel metal hydride, lithium, silver oxide and what not!Cell is a storage form of electrical energy. When more cells are used, it is known as battery, but these words are used interchangeably. These are used where [...]
Resistors are measured in ohms, and have a wattage rating. Resistance value is marked on the resistor in an internationally accepted color code. Normally quarter-watt resistors are used in the following circuits unless otherwise specified. Carbon film and metal film resistors are generally used. Wire wound resistors are used for higher wattage resistors.
Capacitors store a bit of electrical energy and come in many types and varieties. Capacity is measured in terms of Farads named after the great scientist Michael Faraday. As farad is too large a value for most general applications, microfarads (mfd) and nanofarads (nf) are normally used in hobby and consumer applications. Ceramic, polyester, paper, [...]
