Charge created when rubbing materials together

Topic: Electrostatic Induction

Question

October 16, 2016

What charge will be created on following bodies when we rub them against each other
1-metal vs metal
2-insulator vs insulator
3-metal vs insulator

Answer

Much depends on which metals and insulators are used. See Materials that Cause Static Electricity for a list of materials and how well they attract or give up electrons.

Camera acts up from static electricity

Topic: Reducing Static Electricity Shocks

Question

October 1, 2016

It seems that static electricity from my body is causing my camera to crash(freeze) and my viewfinder and screen to function abnormally (become pixelated with flashing bands of colour). Does this make sense? If so what can I do? (Photography is my serious hobby).
Thanks,
Lou

Answer

It is unusual but certainly possible that excess static electricity is causing problems with the electronics in your camera. One thing you can try is to ground yourself before trying to take a picture by touching some metal object. Also, try to avoid polyester clothes when taking pictures. Dry skin on some materials can create static electricity in your body.

I hope these ideas help. Let me know how things turn out. And best wishes with your hobby.

Is electricity from burning coal static?

Topic: Basics of Static Electricity

Question

August 28, 2016

hi, my science teacher and i have recently had an argument about whether or not the electricity generated by burning coal is static as it is a copper brush rubbing on a magnet. he thinks this is not so. i disagree. please settle our dispute

Wyatt - Australia

Answer

Of course burning coal can be used to boil water to turn a generator and create AC or DC electricity. The rotating generator could also be used to create static electricity with a device like a Wimshurst electrostatic generator.

But also, when coal burns, the movement of air from the fire can create static electricity in the air. But I don't think that is what you were talking about.

I hope this helps clarify your discussion.

Why would plastic cause static electricity?

Topic: Causes of Static Electricity

Question

April 20, 2016

At work I was vacuuming dust off pieces of plywood with a shop vac. I was getting some pretty good zaps before I had enough. I taped a wire near the bottom of the plastic hose and put a copper squeeze clamp on the other end and put on the pallet rack. Obviously this worked and eliminated the very unpleasant snappage. My question is, what in the world caused this??? Plastic and wood are good insulators of course and this has not only me but maintenance personnel baffled as well. The lights?

Answer

Static electricity is the collection of electrical charges on the surface of the material. This works best on an insulator. A material that conducts electricity, like a copper wire, will allow the charges to pass through it. It helped drain off the charges from the plastic hose.

Explain how a spark jumps from a finger

Topic: Static Electricity Sparks

Question

April 9, 2016

Explain the spark jumps from a finger to a metal object when the air is dry

Sylvia - Namibia

26919

Answer

A static electric spark will jump from one material to another when the difference in the amount of positive (+) and negative (?) charges is sufficient to cause electrons to overcome the resistance of the air gap between the two materials. The electrons heat the air for a fraction of a second, causing the spark and zapping sound.

This works better with a metal object that will quickly conduct the electrons. Also, in dry air there is much less resistance to the spark that in humid air.

Static in jet airplanes

Topic: Causes of Static Electricity

Question

March 22, 2016

AIRPLANE TODAYS JET AIRCRAFT HAVE INCREASED SPEED AND FUEL FLOW TO THE FILTERS
WHEN THE FUEL LINE NOT BEING IN STRAIGHT LINE AND HAS BENDS= THE STATIC ELECTRICITY BECAUSE OF THE PRESSURE FROM THE FUEL PUMP ,EACH BEND MUST BE TO GROUND OR EARTH STRAP TO ELIMINATE THE CHANCE OF FIRE
THE WIRING LOOM IN THESE AIRCRAFT MUST HAVE A HEAT SENSOR TO THE COCKPIT AS THIS COVERING CAN CAUSE THE PROBLEM OF STATIC ELECTRICITY

Creating static charges in humid Cambodia

Topic: Static Electric Materials

Question

March 2, 2016

Hello,
A colleague of mine in Cambodia is trying to demonstrate static electricity to her students. Cambodia is very hot and very humid. She tried an experiment rubbing a balloon on hair and no static electricity was created. The balloons did not stick to their hair.
Any ideas for how to demonstrate static electricity in a humid place like Cambodia? Thanks!

P. - USA

26835

Answer

It is difficult to create static electricity in very humid weather. However, lightning storms do occur there, and that is extreme static electricity.

If her hair is dry and not oily, using a rubber comb might be more effective to create static electricity.

Rubbing a balloon on wool might create enough static electricity to stick the balloon to the wall, even in humid weather.

Instead of simply demonstrating static electricity, she might let the students experiment rubbing different materials together to see if they can create a charge.

I hope that helps. Let me know if she finds a solution.

Will static electricity attract fibers in home?

Topic: Uses for Static Electricity

Question

February 7, 2016

Hi-

We had an unfortunate occurrence happen in our mobile home. A couple of heat registers came loose from the main trunk line causing underbelly insulation fibers to be sucked up and throughout our home. These fibers are everywhere. One member of our family has been to the Doctor three times and the Emergency Room once. Fibers are embedded into her feet, hands and eye. Doctors do not have a solution or remedy. We do have a cleaning crew scheduled to clean our home in a couple of days. They will use an industrial vacuum cleaner with a three stage HEPA filter to suck the insulation fibers out. My question is this: Could static electricity potentially attract all the fibers to clean our home? You can feel them cling to your body as you are walking through the home. How or what would we use to generate enough static electricity to be effective?

Thank you!

Jim - USA

Answer

Sorry to hear about your problem. High power vacuuming should get out most of the fibers. But there probably will still be some stubborn ones in crevices and such.

Static electricity would attract many of the fibers. The problem is getting a device that would create the static electricity and then move around to attract the fibers.

Note that your bedding, clothes, and other fabrics probably need to be cleaned to get rid of any fibers embedded in them.

Best wishes for cleaning up this nasty problem.

Problems with flyaway hair

Topic: Reducing Static Electricity Shocks

Question

January 27, 2016

The most problem I have is with my hair. It just flys and I can't get it to lay down. My hair is thin anyway and this makes it really difficult to handle.

Tresa - USA

Answer

See Controlling Flyaway Hair for some ideas. I hope that helps.

Methods of discharging electroscope

Topic: Uses for Static Electricity

Question

January 27, 2016

What are the methods of discharging electroscope.

Douglas - Zambia

26724

Answer

You want to draw off the excess changes in the electroscope by touching the metal bulb or disk. You can draw off the charges by touching with your finger or with a metal rod. See Detection of Static Electricity for more information.
