In the figure the solid line shows the driving voltage in an RLC circuit at a particular frequency as a function of time and the dotted line shows the resulting current in that circuit as a function of time. In this circuit
Options:
Answer:
D
Solution:
The current reaches its peak before the voltage, indicating the current leads the voltage. In an RLC circuit, current leads voltage when the capacitive reactance () is greater than the inductive reactance (), which occurs when the driving frequency is below the resonant frequency.
