Introduction

In this scenario, we have a pure inductor with an inductance of 25mH connected to a source of 220V and a frequency of 50Hz. We need to find the inductive reactance, Irms, and peak value of the circuit.

Inductive Reactance (XL)

Inductive reactance is a property of an inductor that opposes changes in current. It is given by the formula XL = 2πfL, where XL is the inductive reactance, f is the frequency, and L is the inductance.

Given:
- Inductance (L) = 25mH = 25 * 10^-3 H
- Frequency (f) = 50Hz

Using the formula, XL = 2πfL, we can calculate the inductive reactance.

XL = 2π * 50 * (25 * 10^-3)
= 2π * 50 * 0.025
= 3.14 * 50 * 0.025
= 3.14 * 1.25
= 3.925Ω

Therefore, the inductive reactance of the circuit is 3.925Ω.

Irms (Root Mean Square Current)

Irms is the effective or average value of the current flowing through the circuit over one complete cycle. It can be calculated using the formula Irms = Vrms / XL, where Vrms is the root mean square voltage and XL is the inductive reactance.

Given:
- Voltage (V) = 220V

To find the root mean square voltage (Vrms), we need to know the type of waveform. Assuming it is a sinusoidal waveform, the formula to find Vrms from the peak voltage (Vpeak) is Vrms = Vpeak / √2.

Given:
- Voltage (V) = 220V

Using the formula, Vrms = V / √2, we can calculate the root mean square voltage.

Vrms = 220 / √2
= 220 / 1.414
= 155.56V

Now, we can calculate the Irms using the formula Irms = Vrms / XL.

Irms = 155.56 / 3.925
= 39.64A

Therefore, the root mean square current (Irms) flowing through the circuit is 39.64A.

Peak Value

The peak value of the current is the maximum value attained by the current during one complete cycle. It can be calculated using the formula Ipeak = √2 * Irms.

Given:
- Irms = 39.64A

Using the formula, Ipeak = √2 * Irms, we can calculate the peak value of the current.

Ipeak = √2 * 39.64
= 55.97A

Therefore, the peak value of the current in the circuit is 55.97A.

Conclusion

In conclusion, the inductive reactance of the circuit is 3.925Ω. The root mean square current (Irms) flowing through the circuit is 39.64A, and the peak value of the current is 55.97A. These values are calculated
