Electronic: The use of active electronic components (integrated circuits, transistors, valves etc) which require a power supply to function. Such "active" components will always be used in conjunction with passive components Earth also known as ground to prevent human from shocks Eddy currents Currents induced into a conducting core due to the varying magnetic field. Efficiency The amount of power given to the load of an amplifier as a % of the power wanted from the power supply. Electric charge Electric energy or Static charge  stored on the surface of a material Electric field A field or force that exists in the space between two different potentials or voltages. Also called electrostatic field. Electroluminescence Conversion of electrical energy into light energy. Electrolyte Electrically conducting liquid (wet) or dry Electrolytic capacitor A capacitor having an electrolyte between the two plates.. Electromagnet A coil of wire usually wound on a soft iron or steel core. When we pass current through the coil a magnetic field is generated. Electromagnetic induction Voltage generated in coil because of relative motion between the coil and magnetic lines of force. Electromagnetic wave Wave that consists of both electric and magnetic changes. Electromagnetism Refers to the magnetic field generated around a conductor when current is passed through it. Electromotive force Force that causes the motion of electrons due to potential difference between two points. Also called EMF Electron Smallest sub atomic particle of negative charge that orbits the nucleus of an atom. Electron flow Electrical current formed by the movement of free electrons towards a positive terminal. Electrostatic Related to static electric charge. Electrostatic field Force field generated by static electrical charges. Emitter The semiconductor region from which charge carriers are injected into the base of a bipolar junction transistor. Other regions are base and collector. Energy Capacity to do work. Equivalent resistance Total resistance of all the individual resistances in a circuit
