For a series LCR circuit, connected to an a.c. source, identify the graph that correspondings to `omega gt (1)/(sqrt(LC))`. Give reason.

Text Solution

Verified by Experts

When `omega gt (1)(sqrt(LC)), X_(L) = omega L`
is large and `X_(C ) = (1)/(omega C)` is small. Therefore, the circuit is inductive. Current I lags behind the applied alternating voltage as shown in Fig.
