In a series RLC circuit that is operating above the resonant frequency, the current
Capacitive reactance is given by
Inductive reactance is given by
At resonance,
But a frequency higher than resonance frequency,
So the circuit behaves as a inductive circuit at a frequency higher that resonant frequency and the current lags behind the voltage in an inductive circuit.
Thus option A is correct.

When temperature of the conductor is increased, then the collision frequency between current carries ( electrons ) and atoms increases. This results in
wires (same length, same area, same material) are connected in parallel and each has resistance, then the equivalent resistance will be
A wire has resistance of . It is cut into two parts and both have are connected in parallel. The new resistance is?
The voltage - current graph of a metallic conductor at two different temperature and is shown below. At which temperature is the resistance higher?
