There is no relationship between electric charge and a radian which is an angular measurement.
One radian is about 57.3 degrees
A flow of electrical charges running through a medium is known as an electrical current.
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.
Those with positive electrical charges, and those with negative electrical charges.
