## Electric Current

Electric Current is the rate of flow of charge through a particular cross sectional area with respect to time. Units for current is ampere (A) 1 A = 1 $C \, S^{-1}$ $$I = \frac{Q}{t}$$ , where I = current, Q = charge, t = time Instantaneous Current $$I = \frac{dQ}{dt}$$ The charge that passes through a given point is …
