In a series RLC AC circult, the frequency of source can be varied. When frequency is varied gradually in one direction from `f_1` to `f_2`, the power is found to be maximum at `f_1`. When frequency is varied gradually at the other direction from `f_1` to `f_3` , the power is found to be same at `f_1` and `f_3`. Match the proper entries from column-2 to column-1 using the codes given below the columns, (consider `f_1 gt f_2`)

To solve the problem, we need to analyze the relationships between the frequencies \( f_1 \), \( f_2 \), and \( f_3 \) in the context of an RLC circuit and how they relate to the types of circuits (capacitive, inductive, resistive) at different frequencies. ### Step-by-Step Solution: 1. **Understanding the Resonance Condition**: - In an RLC circuit, resonance occurs at a frequency \( f_r = \frac{1}{2\pi\sqrt{LC}} \). At this frequency, the impedance is minimized, and the circuit behaves purely resistively. 2. **Analyzing the Given Frequencies**: ...
