Why do you get an electric shock if you touch a doorknob after walking across a carpet?
You build up static electricity by walking across the carpet. When you touch metal doorknob, it releases the stored energy.positive and negative charges. when you drag your feet against carpet you are negatively charged and so the door knob is positively charged so there fore causing an electric shock
What causes a shcok after walking acroiss carpet and touching a metal doorknob?
you build up a charge from dragging your feet and then when you touch the doorknob you discharge the electricity.
Why do you get an electic shock if you touch a doorknob after walking across a carpet?
You get an electric shock if you touch a doorknob after walking on carpet because of built up of extra electrons transferred from the carpet to your feet and then body. The electrons stay built up on you until you touch something that they can discharge on, in this case a doorknob.
Does friction affect on carpet?
Yes. If you drag a static-electric conductive material like cotton socks across a carpet. It will build up a charge large enough to discharge and create a mini-lightning bolt when it comes into contact with something that is grounded.
Why do you get a shock after walking on carpet then touching metal?
Static electricity builds up on the soles of your feet, giving you a charge. When you touch the metal, you are earthed, and the charge is removed. This is felt as a static shock. As the material of your shoes/socks brushes against the carpet, friction causes free electrons to move from the carpet into your body. These electrons will accumulate on your body until you discharge them by touching a path to ground. However, this releases energy, which you feel as a shock. This energy is potent enough to be felt, heard, and even seen. This will only happen if your shoes/socks are of the right material and the air is dry. You build up static electricity by walking across the carpet. When you touch metal doorknob, it releases the stored energy. When you drag your feet against carpet you are negatively charged and so the door knob is positively charged so there fore causing an electric shock
If walking on a carpet with socks what will reduce the charge build up?
Don't drag your feet
Why are you more likely to receive a shock after walking across a carpet when the air is dry when the air is humid?
Walking across the carpet causes charges to build up on your body. On a humid day the water molecules in the air tend to be attracted to the excess charge, even though they are neutral they are polar and will still move toward a source of charge. when they contact the charged object they pick up some of the excess charge and carry it away. This constant draining of charge makes it much harder to build up the proper amount of charge to get a nice noticeable shock.also because it its like that
What is happening when you walk across a carpet and receive a shock when you touch a metal object?
Walking across a nylon carpet can cause charge separation between you and the carpet. You take on an electrostatic charge as a result. Touching a door knob allows that charge you accumulated to neutralize via a discharge event. The static discharge is the electric shock.
What is a buildup of charged particles?
It is when you charge a capacitor. When you walk across a carpet on a dry day, you build up a charge. It is discharged when you touch something.

What causes a shcok after walking acroiss carpet and touching a metal doorknob?
you build up a charge from dragging your feet and then when you touch the doorknob you discharge the electricity.
What is charge on our body?
I assume that 'charge' refers to the build up of static electricity. Walk across a nylon carpet and touch someone, and a spark of static electricity will give both of you a shock.
Why can you get a shock by touched a doorknob after walking on a wool carpet?
You build up static electricity by walking across the carpet. When you touch metal, it releases the stored energy. positive and negative charges. when you drag your feet against carpet you are negatively charged and so the metal is positively charged so there fore causing an electric shock
Why do you get an electic shock if you touch a doorknob after walking across a carpet?

Do you get shocked when an object is positivly charged?
no but You build up a negative charge as you drag your feet across the carpet. To balance you back out, you donate the extra electrons to the protons on the doorknob, which gives you a shock
Does friction affect on carpet?
Yes. If you drag a static-electric conductive material like cotton socks across a carpet. It will build up a charge large enough to discharge and create a mini-lightning bolt when it comes into contact with something that is grounded.
How does walking across a carpet make static electricity?
The voltage can be 5000 volts or more, but there is no danger because the amount of electric charge is small. An average human body has a capacitance of about 100 picofarads so that with 5000 volts the charge is only 500000 picocoulombs or 0.5 microcoulombs, which represents a current of 1 milliamp flowing for only half a millisecond.
