There is no relationship between electric charge and a radian which is an angular measurement.
One radian is about 57.3 degrees
Meter is a unit of length. Radian is a unit of angle. They don't relate.
Electrical charges will not flow. The considered to be held stationary.
A flow of electrical charges running through a medium is known as an electrical current.
Electric current is defined as the movement of electrical charges.
That is the electric energy. It is called the electricity
magnetism. Moving electricity generates magnetism
The three types of electrical charges are positive, negative, and neutral. Positive charges are carried by protons, negative charges by electrons, and neutral charges have an equal number of protons and electrons.

The form of energy carried by moving electrical charges is electrical energy. It is the energy associated with the flow of electrons through a conductor.
The radian is 0.523598776
