You can derive it from accelerating an object to a certain speed. Assume constant acceleration (and therefore constant force), and calculate how much work (force x distance) you need to get the object to a specific speed.
Calculating system inertia by mutiplying the Inertia Time Costant [Sgn] of every single generator to calculate the inertia of the generator and sum all inertias to calculate the whole system inertia Calculating system inertia from the RoCoF (post fault calculation)
E=hv where h is Planck's constant (6.62 X 10~27 erg -sec) and v is the frequency
d = 1/2 a t2 where d is distance traveled a is the constant acceleration t is the time You can calculate the value of "a" by dividing "v" by "t".
Because the speed of light in a vacuum is constant(c). hence the formula, v=f.w, where v is velovity, f is frequency and w is wavelength, can be used to calculate the frequency.
Because they have same structure.(Rock salt structure)

A resistor by itself has no time constant. For a circuit to have a time constant it must contain either capacitors or inductors.

The time constant of an RL series circuit is calculated using the formular: time constant=L/R
