ELECTRIC CURRENT

HEAT

MOVEMENT OF ELECTRONS THROUGH AN ELECTRICAL CABLE IS SLOW AND DISORDERLY

JOULE EFFECT : E=I2 X R X t

LIGHT

LIGHT-EMITTING DIODES

Has layers of semiconductor materials when electricity is applied to the led then the electrons cross over into the active layer

FLUORESCENT BULBS

It has a metalic fillament, when the electric current passes through the filament electrons are emited into the inert gas

INCASDECENT BULBS

electric current passes through the metalic filament of the bulb

ELECTROMAGNETIC EFFECTS

Michael Faraday noticed that electricity could be generated by using a magnet anelectrical conductor this allows us tu build dynamos and alternators

SOUND

We can transform sound into electric current using electromagnetical devices such us bells, some of these de vicesare based on the piezoelectric effect
