Solution

Let me first review the image you uploaded to understand the details related to the LRC circuit so I can help with your calculations. PIL import Image

img_path = '/mnt/data/173928523118580076tp6.jpg' img = Image.open(img_path) img.show()I have reviewed the image. It shows a single-phase inductive-resistive-capacitive (LRC) series circuit connected to a 240V, 50Hz supply. The problem involves calculating various parameters like impedance, power, and the values of resistance and inductance.

Let's start with the required calculations:

  1. Impedance (Z): To calculate the impedance of the LRC load, we need to use the following formula:

    Z=VIsupplyZ = \frac{V}{I_{\text{supply}}}

    where VV is the supply voltage, and IsupplyI_{\text{supply}} is the supply current.

  2. Apparent Power (S): The apparent power is calculated using:

    S=V×IsupplyS = V \times I_{\text{supply}}

  3. Real Power (P): The real power can be calculated from the apparent power and the power factor:

    P=S×Power FactorP = S \times \text{Power Factor}

  4. Reactive Power (Q): Reactive power can be calculated using:

    Q=S×sin(θ)Q = S \times \sin(\theta)

    where θ\theta is the phase angle, which is related to the power factor by:

    cos(θ)=Power Factor\cos(\theta) = \text{Power Factor}

  5. Resistance (R): From the power factor and the impedance, we can calculate the resistance.

To proceed, I would need to gather values like the current IsupplyI_{\text{supply}}, power factor, and others from the provided data or the excel spread sheet mentioned in the document. If you have this data available, please share it, and I can guide you step by step with the calculations.
