**Category:** Electromagnetism

**Subtype:** Alternating Current (AC) Circuits

**Problem Description:** This problem involves an AC generator connected to a circuit consisting of a resistor (R), an inductor (L), and a capacitor (C) in series. It states that the effective current in the circuit is the same at two different rotational speeds of the generator (360 RPM and 800 RPM). The problem asks for the rotational speed \( n_0 \) at which the effective current reaches its maximum value. 

**Objective:** Determine the rotational speed \( n_0 \) that maximizes the effective current in the circuit. The options provided are various speeds in RPM.
