Answer: Natural gas doesn’t have an energy source—it IS an energy source! Natural gas is a fuel that’s used to heat buildings, cook food, dry clothes, heat water, and even to help produce electricity. In fact, about 20 percent of the electricity that SCE provides to our customers is generated with the help of natural gas. You can learn more about how natural gas and other fuels are used to produce electricity by visiting the Producing Electricity page of our website:

Answer: Electricity is a process that begins with electrons that orbit the center of atoms. The electrons in some materials – such as copper and other metals – are only loosely attached to their atoms, allowing electricity to travel through these materials easily. When an outside force is applied to these materials, 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: Inside a light switch are two wires. One wire carries the electric current to the switch from a fuse or circuit breaker. The other wire carries the current from the switch to the light socket. When you flip the light switch "On" it connects these two wires, allowing the current to flow to the light bulb.

Answer: Anonymous Yes, it’s an excellent idea to have an emergency kit! Even the most reliable electrical service can go off during extreme weather events, earthquakes or other natural disasters, so it’s always smart to have on hand the things you’ll need when the power is down.

Answer: A technician will use what’s called a solar inverter. This type of inverter removes the electrical power, either from your solar panels or batteries, and turns it into AC power, that is ready and usable for your household appliances.

Answer: You can safely plug several small devices that use relatively little power—like a laptop, printer, phone charger, and a desk lamp—into a power strip with multiple outlets. However, it’s UNSAFE to do this with items that use a lot of power such as: a large-screen TV, an electric space heater, or a hair dryer. Also, before plugging anything into an electrical outlet, always ask a parent or guardian for help.

Answer: Since "t" refers to time and time doesn't stop, the t in Faraday's Law is never constant, whether or not the magnet is in the coil.

Answer: The chips vary in size, but they are typically between 4 and 6 square millimeters.
