Question
**Determine the following for the network below.**

A schematic of an electrical network is shown. It includes a voltage source \( E = 50 \, \text{V} \angle 0^\circ \) with a frequency \( f = 60 \, \text{Hz} \). The circuit contains three components in series:

- A resistor \( R \) with a resistance of \( 3 \, \Omega \)
- A capacitor \( X_C \) with a reactance of \( 5 \, \Omega \)
- An inductor \( X_L \) with a reactance of \( 9 \, \Omega \)

**Find the average power delivered to each element.**

1. \( P_R = \) [Input Box] units
2. \( P_C = \) [Input Box] units
3. \( P_L = \) [Input Box] units

Please calculate the power delivered to each component using appropriate formulas for resistive and reactive elements in AC circuits.

**Reactive Power Calculation**

1. **Find the reactive power for each element.**
   - \( Q_R = \) [______] units
   - \( Q_C = \) [______] units
   - \( Q_L = \) [______] units

2. **Find the total complex power in rectangular and polar form.**
   - \( S_T = \) [______] units [______] + j [______] units
   - \( S_T = \) [______] ∠ [______]° units

3. **Find the total apparent power.**
   - \( |S_T| = \) [______] units [______]

4. **Using only power quantities, determine the power factor.**
   - pf = [______] (lagging or leading) [______]

**Note:** On your handwritten work, sketch the power triangle to visualize the relationships between the real, reactive, and apparent power.
