Electric Circuit – Components & Symbols

Components that are Commonly Found in Electric Circuits:

An electric circuit usually comprises the battery (cell) which is the source of electric energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More, a key or switch to start or stop current flow, an ammeter to measure current, a voltmeter to measure potential difference, a resistor and a rheostat to vary the current.

These components are connected as shown in the image below;
