What is the formula to calculate the velocity of electrostatic discharge?

The velocity of electrostatic discharge (ESD) is not typically expressed with a single formula, as it can vary widely depending on the materials involved and the conditions of the discharge. However, one way to estimate the velocity is through the relationship between electric field strength (E) and the mobility of charge carriers (μ), given by ( v = μE ), where ( v ) is the drift velocity of the charge carriers. The actual speed of an ESD event can also depend on factors such as the geometry of the discharge path and the dielectric properties of the materials involved.
