The following series L-C-R circuit, when driven by an emf source of angular frequency 70 kilo-radians per second, the circuit effectively behaves like

Step-by-step solution

Impedance, Z= (X_L X_C )^2+R^2 or Z= ( L 1 C )^2+R^2 Inductive reactance aligned X_L & = L=70 10^3 100 10⁻⁶ & =7 aligned Capacitance reactance aligned X_C & = 1 C = 1 70 10^3 1 10⁻⁶ & = 1 7 10⁻² = 10^2 7 = 100 7 aligned As X_C>X_L Hence, circuit behave like as R-C circuit.
