Answer: Yes, the human body is a good conductor of electricity because it is 60-70% water.  This means that if you touch electricity, electricity will flow through you, and you will be badly hurt.

Answer: Many of our daily activities require electricity, such as lighting our homes; cooking with a toaster oven, range, or microwave; keeping food cold with a refrigerator; washing clothes; using a computer; watching TV; and charging our devices.  Electricity  powers our modern lives!

Answer: A good question, and you’re not the first person to ask it! Most electricity in this country is made (or produced) at power plants where fossil fuels (coal, oil, natural gas) or renewable energy sources (such as water, wind, biomass, or geothermal) are used to turn turbines. The turbines turn electromagnets that are surrounded by heavy coils of copper wire. The moving magnets cause the electrons in the copper wire to move from atom to atom, generating electricity. Electricity can also be produced from sunshine, using special panels that convert sunlight into electricity. You can see these panels on the rooftops of many Southern California homes, businesses, and warehouses.

Answer: Lightning travels at a speed of 220,000 miles per hour, so if you can’t beat that, then unfortunately, you can’t outrun lightning. Lightning can be deadly. Reduce the chances of being struck while indoors by not touching windows, plumbing, metal objects, or electronics during a lightning storm. If you’re outside, get indoors when a storm is approaching. Read about what to do if you can’t get to shelter on our website here.  And read about one lucky lightning shock survivor’s tale on our website here.

Answer: It takes a LOT of watts to power a factory!  Electricity use for factories is measured in megawatts, which are units of one million watts. An integrated cement plant can use 650 megawatts. Other types of factories may use much more electricity or much less, depending on their size, production load, and other factors.

Answer: Plastic does indeed help prevent electric shocks. For example, on our home appliances and power cords, special insulating plastic keeps us from contacting the electricity inside. If this plastic becomes damaged in any way, you risk coming in contact with a bare electrical wire, which could cause shock and injury. That’s why you should always report a damaged cord or appliance to an adult.

Answer: A magnet generates a magnetic field around itself because of the way atoms are arranged. An electromagnet only generates a magnetic field when an electric current is passing through it.

Answer: There are advantages and disadvantages of placing power lines underground. While low-voltage lines are sometimes placed underground in newer neighborhoods, it is not the preferred method for power lines that carry electric power over long distances. Please see our series of Q&A’s on the subject of overhead vs. underground click here for more specific information.

Answer: Very fast! If you could travel through wires as fast as electricity does–about 300,000 km per second–you could go around the world eight times in the time it takes to turn on a light switch.

Answer: Maddi asked this question just recently, but I’ll repeat my answer for you here. Most electricity in this country is produced at power plants where fossil fuels (coal, oil, natural gas) or renewable energy sources (such as water, wind, biomass, or geothermal) are used to turn turbines. The turbines turn electromagnets that are surrounded by heavy coils of copper wire. The moving magnets cause the electrons in the copper wire to move from atom to atom, generating electricity.

Answer: Here is a simple example of energy conversion: When you boil water using an electric teapot, electrical energy is converted to thermal energy, or heat. Energy conversion also occurs within your body, as your digestive process converts the chemical energy of food to the mechanical energy that you use to move and the thermal energy that keeps you warm.

Answer: The Expert does not recommend putting wet socks on an electric radiator. The socks could catch fire or create a shock hazard. Always keep socks and other flammable items, whether wet or dry, away from electric heaters.

Answer: This is one of our most popular questions, and it’s an important one. Electricity is a process that begins with electrons that orbit the center of atoms. When an outside force is applied, electrons can break free and get “bumped” from one atom to the next. The resulting continuous flow of electrons from atom to atom results in electricity. Electric power plants rely on this atomic process. Fossil fuel energy sources (such as coal, oil, or natural gas) or renewable energy sources (such as water or wind) are used to turn turbines. The turbines turn electromagnets that are surrounded by heavy coils of copper wire. The moving magnets create the outside force that causes the electrons in the copper wire to move from atom to atom, generating electricity.

Answer: You’re right, Grace! Everything is indeed made out of particles! Unfortunately, even if we could make a magnifying lens strong enough to observe the electrons that generate electricity, we would not be able to see them because as light (photons) strikes the electrons, it changes their energy and their position.
