CURRENT ELECTRICITY - L0

If C,R,L and I denot capacity resitance, inductance and electric current respecitively, the quantities having the same dimensions of time are (a) CR , (b) L//R , (c) sqrt(L//C) , (d) LI^(2)

Let [in_(0)] denote the dimensional formula of the permittivity of vacuum. If M= mass, L=length, T=Time and A= electric current, then:

In L-R circuit l=l_(0)[1-e^(-t//lamda)] Here l= electric current in the circuit. Then
