We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

So let’s say we have a moving charge (with a velocity v and charge q) in a region with both an electric and magnetic field. In that case, the total force on the charge can be calculated with the ...

Electric and magnetic fields are both components of an electromagnetic field. These two components occupy different planes relative to the cause of the electromagnetic field, for example a moving ...

The Tesla Model 3. "In theory, one could drive for an unlimited amount of time without having to stop to recharge," Fan explained. "The hope is that you'll be able to charge your electric car ...

Scientists have known about the minuscule electric charge carried by living things, such as insects, for a long time. However, the idea that an electric bug-aloo could alter the charge in the air ...

Using very high voltages—in the plane’s case, 40,000 volts—the thruster generates ions in the air around two electrodes. The electric field created between these throws the ions from a ...

This animation shows how the ambipolar electric field works. The most abundant gas in the lower atmosphere, the part we live in, is nitrogen (N2, shown around seven seconds).
