CURRENT ELECTRICITY - L15

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:

Tutorial on L1 to L3 of Current Electricity

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

(a) Write down the formula which relates electric charge, time and electric current. (b) A radio set drawns a current of 0.36A for 15 minutes. Calculate the amount of electric charge that flows through the circuit.

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.

Using mass (M) , length (L) , time (T) , and electric current (A) as fundamental quantities , the dimensions of permitivity will be
