Power a Light with Static electrical power - use static power to light up a fluorescent light bulb.

Static electrical power can administer enough power to irradiate up a light bulb. If girlfriend have ever before experienced a small zap from static electricity, this quantity of energy is qualified of powering a fluorescent light pear for a brief time.

*

Step 1: punch up a balloon and tie turn off the end.

*

Step 2: obstacle the balloon vigorously against the hair on her head.

Step 3: get in a dark room.

*

Step 4: Touch the balloon versus the two steel electrode prongs ~ above the bottom that the fluorescent irradiate bulb.

*

Step 5: watch what happens when the static electrical energy discharges native the surface ar of the balloon into the fluorescent irradiate bulb.

Step 6: Repeat rubbing the balloon to add much more static electrical energy to the surface of the balloon. If careful, the balloon can be held against the light bulb together it is rubbed against hair. As the balloon surface ar builds up enough static power it will discharge into the light pear frequently, bring about light.

Extra electron from the hair transfer to one area top top the surface ar of the balloon providing it a an adverse charge. The majority of the surface of the balloon still has actually a neutral charge. If the balloon is rubbed because that longer, more of the surface will construct up a an adverse charge.

The fluorescent light bulb acts together an electric circuit, enabling the power to discharge from the surface ar of the balloon right into the light circuit. Within the fluorescent bulb the electrons travel v the light tube they bump versus mercury gas electrons. Eventually this reasons the mercury gas electron to relax photons i m sorry is the resource of the light. The light only occurs until every one of the static electrical energy charge indigenous the surface ar of the balloon wherein the light bulb electrode prongs are poignant is supplied up. If you move the prongs to one more area the the balloon surface you will see one more light increase in the pear if there space still an adverse charged electron there.
