**Category:** Electromagnetism

**Subtype:** RLC Circuits (Resonance in AC Circuits)

**Problem Description:** This problem involves an RLC series circuit connected to an alternating voltage source. Initially, the circuit is at resonance at a frequency \( f_0 \). As the frequency of the AC voltage is increased while keeping other parameters constant, the problem asks which statement about the circuit's behavior is incorrect. The statements concern the effective current, effective voltage across the resistor, effective voltage across the capacitor, and the power factor of the circuit. 

**Key Concepts:**
- Resonance in RLC circuits
- Behavior of current and voltage in response to frequency changes
- Power factor and its relation to circuit components

**Objective:** Identify the incorrect statement regarding the effects of increasing frequency on the circuit's parameters.
