CURRENT ELECTRICITY - L9

L-6 to L-9

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)

L-9 to L-11

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

L4 To L6 Current Electricity

Tutorial on L1 to L3 of Current Electricity

The magnetic energy stored in an inductor is given by E=1/2L^(a)l^(b) . Find the value of 'a' and 'b' . Here L= self-inductance l= electric current.
