Most lightning strikes are negatively charged and make up for about 95% of total strikes. Thunderstorms that carry more positive charges in the summer tend to be stronger storms too.

Does lightning strike from the sky down, or the ground up? The answer is both. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.

Description. Atmospheric electricity is always present, and during fine weather away from thunderstorms, the air above the surface of Earth is positively charged, while the Earth’s surface charge is negative.

It probably because at the inner core of the Earth, the temperature and pressure is so high that the atoms there are ionized. So the inner part of earth is posstively charged.

Ans: YES. Earthing can be used as a neutral wire but a neutral can not be used as an earthing wire….Difference Between Earthing and Neutral:

The neutral is always referenced to ground at one, and ONLY one, point. If you touch the neutral to ground anywhere else, you will create the aforementioned ground loop because the grounding system and the nuetral conductor are now wired in parallel, so they now carry equal magnitudes of current.

Whenever you have an auxiliary panel the neutral and ground should not be tied together because the ground wire becomes a parallel path for current with the neutral wire (any current going through the neutral wire will be shared with the ground wire because they have the same connections at both ends).

In Short if neutral wire touches a earth wire, An earth wire carrying load current is a risk of electric shock because a person touching this earth may present an alternative path for the load current and thus the risk of electric shock.

Without the earth wire, if a fault occurs and the live wire becomes loose, there is a danger that it will touch the case. The next person who uses the appliance could get electrocuted . The earth wire is therefore connected to the case and is attached to a metal plate or water pipe underground.

If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.

If the live wire becomes loose and touches the metal case, the very large current flows through the earth wire and blows the fuse in the plug, breaking the circuit. The earth wire provides an alternative path for the current. They use an electromagnet to break the circuit if the current difference becomes too large.

No, touching the ground wire will not shock you unless it is not properly bonded AND there is a faulty piece of equipment attached to it. This! Remember that voltage is relative. This may be a few volts if there’s standing earth faults – but generally anything less than 50V on normal, dry, skin is perfectly safe.

The CPC (earth) is not a live conductor, so it does not need insulating in the way live and neutral do, as the earth sleeving is an insulator. It needs protecting from its surroundings, not protecting someone from the cable.

Electricity doesn’t care if your grounded or not. If you are a potential path to complete a circuit, by yourself or in parallel or series with an existing circuit, then when you put yourself in that position you can be electrocuted regardless of being grounded or not.

Selected properly, insulating rubber gloves will do the job of protecting the worker against electrical shock. Do not forget about leather protectors, for they are an essential part of wearing and using the insulating rubber gloves correctly. As mentioned above, determining gloves’ size is also important.

Power lines are not insulated and you should always avoid contact with them. It is quite possible for people to get electrocuted if you touch power lines.

Lotion: After a shower or bath, add moisture to your body. The lotion will act as a barrier and prevent static electricity from building up. Rub lotion on your hands, legs and even a small amount to your hair. Then gently rub your clothes to diffuse shocks directly there as well.

Some objects such as wool, glass, human skin and hair are more likely to accumulate electric charges and have static electricity. Increasing the humidity levels with a humidifier can help mitigate prolonged buildup of static charges in the body. “You can add humidity to the air to help with this.

Some amount of static build up is inevitable, but you can take steps to reduce the static charge.

1. Wear natural fibers.
2. Go barefoot indoors.
3. Wear leather soled shoes.
4. Pick up your feet when you walk across carpet.
5. Moisturize your skin.
6. Humidify the air.
7. Have live plants indoors.

Touch a metal object using another metal object to release static discharge. This allows sparks from the discharge to affect the metal object, and not your skin. For example, touch a doorknob using a key instead of your hand at first to lower the risk for electric shock.

To prevent ESD damage, you should discharge static electricity from your body before you interact with any of your computer’s internal electronic components, such as a memory module. Handle all electrostatic sensitive components in a static-safe area.

Static shocks are more common when it’s cold and dry. This dry, cold air holds less water vapour than warm summer air. So, when you touch something like a metal doorknob or car door, those extra electrons will rapidly leave your body and give you the shock.

Moisture in the air prevents static electricity from building up, and that’s where humidifiers come in. Maintaining an optimum humidity level around 30 or 40 percent can significantly reduce static electricity.

Static electricity is caused by your body picking up free electrons as you walk on the rugs. When you have extra electrons on your body and you touch a metal conductor, such as a door handle, the electrons flow into the object and you get a static shock.

When you get out of the car, you slide your body across the seat, and that can leave both the seat and your body statically charged. If the air is cold and dry enough, the charge will quickly and violently transfer from your body into the car’s metal and shock you.
