The image shows an **RLC Parallel Circuit** task where we need to solve for various parameters of the circuit based on the provided schematic and measured data. Here's a breakdown of the task and how to approach it:

### Given Data:
- **Supply Voltage (Vs)**: 12V
- **Resistor (R)**: \( 33 \, \Omega \)
- **Inductor (L)**: \( 91 \, \text{mH} \)
- **Capacitor (C)**: \( 220 \, \mu \text{F} \)

### Task Breakdown:

1. **Construct the RLC Series Circuit and Measure:**
   - **(A) Supply Voltage**: Given as **12V**.
   - **(B) Branch current magnitude and angle for the resistive component**:
     To calculate this, use Ohm’s Law \( I_R = \frac{V}{R} \). For phase angle, since it's purely resistive, the angle \( \theta_R = 0^\circ \).
   - **(C) Branch current magnitude and angle for the inductive component**:
     The inductive reactance is \( X_L = 2\pi fL \). Then, the current \( I_L = \frac{V}{X_L} \). The phase angle for an inductor is \( \theta_L = +90^\circ \) (current lags voltage).
   - **(D) Branch current magnitude and angle for the capacitive component**:
     The capacitive reactance is \( X_C = \frac{1}{2\pi fC} \). The current \( I_C = \frac{V}{X_C} \). The phase angle for a capacitor is \( \theta_C = -90^\circ \) (current leads voltage).

2. **Using Measured Values:**
   - **(E) Draw and label the RLC series phasor diagram**: This would involve plotting the vectors for \( I_R \), \( I_L \), and \( I_C \) with appropriate phase angles. 
   - **(F) Determine supply current magnitude via phasor diagram**: Use vector addition to sum the phasor currents \( I_R \), \( I_L \), and \( I_C \).
   - **(G) Determine the circuit phase angle via phasor diagram**: Calculate the overall phase angle \( \theta \) using the phasor sum of the currents.
   - **(H) Determine the circuit phase angle via phasor diagram**: Repeated to ensure clarity in the calculation process.
   - **(I) Determine the relationship between supply voltage and circuit current**: This involves understanding whether the circuit is capacitive or inductive based on the resultant phase angle.

### Formulas:

- **Resistive Current**: \( I_R = \frac{V_s}{R} \)
- **Inductive Reactance**: \( X_L = 2\pi f L \)
- **Capacitive Reactance**: \( X_C = \frac{1}{2\pi f C} \)
- **Inductive Current**: \( I_L = \frac{V_s}{X_L} \)
- **Capacitive Current**: \( I_C = \frac{V_s}{X_C} \)
