**Category:** Electromagnetism

**Subtype:** AC Circuits

**Problem Description:** This problem involves analyzing an alternating current (AC) circuit consisting of a non-purely inductive coil, a capacitor, and a resistor connected in series. The task is to determine the total resistance of the circuit based on the given effective current and the voltage-time graph obtained from an oscilloscope. 

**Key Elements:**
- Given: Effective current \(I = 3 \, \text{A}\)
- Components: Inductor, capacitor, and resistor in series
- Objective: Find the total resistance of the circuit

**Options for Total Resistance:**
A. \(50 \sqrt{3} \, \Omega\)  
B. \(100 \, \Omega\)  
C. \(150 \sqrt{3} \, \Omega\)  
D. \(50 \, \Omega\)
