When a capacitance is connected in series with a series L-R, a.c. circuit, the total impedance of the circuit

When a capacitor of small capacitance is connected in series with L-R circuit. The alternating current in the circuit increases. Explain why ?

If resistance R =100 Omega, inductance L = 12mH and capacitance C=15muF are connected in series to an AC sources, then at resonance the impedance of circuit is

If resistance R =100 Omega, inductance L = 12mH and capacitance C=15muF are connected in series to an AC sources, then at resonance the impedance of circuit is

In the series L-C-R circuit shown ,the impedance is

In an ac circuit, an inductor, a capacitor and a resistor are connected in series with X_(L) = R = X_(c) . Impedance of this circuit is :

In an A.C. circuit, resistance = 12 Omega and capacitance reactance = 9 Omega are connected in series, then the value of impedance of a circuit will be ..........

An L-C-R series A.C. circuit is tuned to resonance. The impedance of the circuit is ……
