It's time for another physics example. In this case, I am going to calculate the electric field due to an electric charged rod. Of course you could do this analytically using a bit of calculus. This ...

If you hang around with physics people long enough, some­one eventually will bring up Maxwell's equations. Maybe as part of a joke, or on a T-shirt or a tattoo. But they'll be somewhere. So even if ...

The electric potential at any point in space made by a point charge Q is presented by the formula given below. It is the electric potential energy per unit charge. The electric potential at any point ...
