Which can not produce static electricity?

Question

Options are 1. The use of rubber tyre vehicles 2. Humidification process

Answer 1

Static electricity is the imbalance of positive and negative charges.The contact between two different materials produces the electric charge eg Rubbing of two different materials increases the contact area between them and helps in the process of generating the electric charge.

But if there Increase the humidity, the static electricity can not be produced in Humidification Process due to the moisture presence. On the other side the rubber Tyres can produce the electric charge in dry conditions due to contact as explained in the starting.

Answer 2

The rubber tires on a car or truck rolling over the road build up a static charge on the body of the car or truck, the same as when a person with rubber soled shoes rubs his feet on a carpet, and then touches a metal doorknob.
The static charge builds up on your body unless your shoes have leather soles, or soles of a material that do NOT insulate you from the ground, but that ground you so that the static charge dissipates to the ground.......That is why many cars or trucks use grounding straps or chains.
You will build up this static charge no matter what the humidity is, however when you reach for a piece of grounded metal to touch, if there is a lot of humidity in the air, then the static charge must have more energy to leap the gap between your hand and any metal due to the moisture. Because the moisture in the air acts as a sort of insulator, the electricity cannot jump the gap to shock you, and just bleeds off when you grab the metal.

Answer 3

Humidifiers generate, guess what, humidity; i.e. they evaporate water into the air. Damp air conducts electricity a little, thus static electricity can not build up in damp air.

Rubber "tyre" vehicles generally do not build up static electricity either, even in the desert where there is very low humidity, although there is an accessory (a chain that touches the ground when stopped) sold to prevent this non-existent problem.

Since you spell "tyre", you are probably in England, where the high humidity would prevent the generation and accumulation of static.

Thus, if you are in England, the answer is "both".

Answer 4

In this example I have got to say the newspaper isn't the perpetrator. Several matters have got to be in situation to arrive ESD stages ample to overpower the protetctions diodes constructed in to the chips we use at the moment. First of all of the friction need to be particularly top and a garage medium furnished for the cost construct up. Once the cost is ample it might have got to be located in this kind of means as a way to discharge by way of the chip. We layout our forums with flooring planes and again EMF diodes at the vigour circuits for that very cause. The mounting flange to your video card is securely bonded to the bottom aircraft and the paper unquestionably contacted this good. It is much more likely that the recipient of your card became off the vigour however didn't unplug the give from the wall. This leaves the motherboard are living for quite a lot of makes use of adding onboard reminiscence. The video card commonly has direct entry to the onboard reminiscence and plugging it on this means could have broken his reminiscence at the motherboard. He could have even broken the cardboard itself. If he was once unsure together with your packaging he will have to have lower back it on the ones grounds - or a minimum of contacted you first earlier than powering the gadget. He proceeded with out warning. Because you haven't any manage over how the buyer established the product, the legal responsibility is his. Caveat emptor. That being stated, the cardboard is most likely good enough - he demands to investigate his on board reminiscence and make sure the gadget drivers are updated.
