CURRENT ELECTRICITY - L1

Refer to the circuit diagram and the corresponding graphs. The current rises when key K is pressed. With R= R_(1) and L=L_(1) the rise of current is shown by curve(1), while curve(2) shows the rise of current when R=R_(2) and L = L_(2) . The maximum current is same for both curves, then:

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

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.

Find the steady - state current through L_1 in the figure

The voltage-current graphs for two resistor of the same meterial and the same radius with lengths, L_1 and L_2 are shown in fig 5.2. if L_1 gt L_2 , state with reason which of these graphs represents votage- current change of L_1.
