Glossary of electrical terms. Poles are fundamental to understanding how electricity is created.
Single Pole Switch Lighting Circuits How To Wire A Light Switch
What is pole in electrical terms. A utility pole is a column or post used to support overhead power lines and various other public utilities such as electrical cable fiber optic cable and related equipment such as transformers and street lightsit can be referred to as a transmission pole telephone pole telecommunication pole power pole hydro pole telegraph pole or telegraph post depending on its applicationa stobie pole is a multi purpose pole made of two steel joists held apart by a slab of concrete in the. Polarity a collective term applied to the positive and negative ends of a magnet or electrical mechanism such as a coil or battery. The load bearing. When you wire a switch to a 120 volt circuit. For example a regular 120 volt outlet is single phase so it uses a 1 pole breaker. Electric poles wooden electric pole.
Thus the total terminal voltage of the coil will be nothing but the direct arithmetic sum of these two emfs. Alternating current ac the type of mains electricity used in the uk having a cyclical current waveform. In earlier period wooden poles were used for 400 volts and 230 volts lt. That means that it connects to just a single leg of the power supply. Normally used in uk houses at 240v rms alternating at 50 times per second 50 hertz. Either how much electricity an appliance will use or a circuit fuse mcb cable connectors etc can handle.
In this situation two opposite sides of the coil lie under two opposite poles. It is how many legs of electrical power a particular circuit uses. Electrical wiring difference between single pole double pole switches a 240 volt circuit needs a double pole switch. If the coil span is equal to the pole pitch then the armature winding is said to be full pitched. Phases describes an aspect of alternating current. Pole definition a long cylindrical often slender piece of wood metal etc.
Poles and phases are used to describe very different aspects of electricity. Pole one or two points of a magnet at which its magnetic attraction is concentrated. Line and 11 kv. Ampere a or amp unit of electrical current. Poles are used in 11 kv and 400230 volt system to a large scale apart from. Two hot wires with a voltage of 240 volts between them feed electricity.
In the us typically any. Steel tubular electric pole. Hence emf induced in one side of the coil will be in 180 o phase shift with emf induced in the other side of the coil. The difference between single pole and double pole switches. In electrical engineering many terms are used to describe how electrons and electricity behave.
