In a series RLC circuit, what happens to the current when the frequency is increased beyond the resonant frequency?
Correct Answer: Current decreases
- Step 1: Understand what a series RLC circuit is. It has a resistor (R), inductor (L), and capacitor (C) connected in a series.
- Step 2: Know what resonant frequency means. It is the frequency at which the circuit can oscillate with maximum current.
- Step 3: Recognize that at resonant frequency, the effects of the inductor and capacitor cancel each other out, allowing maximum current to flow.
- Step 4: Learn that when the frequency is increased beyond the resonant frequency, the inductor's effect becomes stronger than the capacitor's effect.
- Step 5: Realize that as the circuit becomes more inductive, it opposes the flow of current more, leading to a decrease in current.
