The graphs shown in Fig. represent the variation of opposition offered by the circuit element of the flow of a.c. with frequency of applied e.m.f. Iddntify the circuit element .

Answer» In Fig, opposition to current does not vary with frequency. The circuit element must be a pure resistor. In Fig, opposition to current increses directly with applied frequency. The circuit element must be a pure inductor `(X_(L) = omega L = 2 pi v L , X_(L) prop v)`.
