1. What is Voltage Division in Two Inductors?

Voltage division in two inductors refers to the distribution of voltage across inductors connected in series in a circuit. The voltage across each inductor is proportional to its inductance value when compared to the total inductance in the circuit.

2. How Does the Calculator Work?

The calculator uses the voltage division formula:

Where:

• \( V_{L1} \) — Voltage across inductor 1 (Volt)
• \( V_s \) — Source voltage (Volt)
• \( L1 \) — Inductance of first inductor (Henry)
• \( L2 \) — Inductance of second inductor (Henry)

Explanation: The formula calculates the voltage drop across the first inductor in a series circuit based on the ratio of its inductance to the total inductance.

3. Importance of Voltage Division Calculation

Details: Understanding voltage division in inductive circuits is crucial for circuit analysis, design, and troubleshooting in electrical engineering applications.

4. Using the Calculator

Tips: Enter source voltage in volts, and both inductance values in henries. All values must be positive and greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Does this formula work for AC circuits?
A: This formula applies to DC circuits. For AC circuits, impedance rather than pure inductance should be considered.

Q2: What if the inductors are not ideal?
A: Real inductors have resistance and other parasitic elements that may affect the actual voltage division in practical circuits.

Q3: Can this formula be extended to more than two inductors?
A: Yes, for multiple inductors in series, the voltage across any inductor is \( V_s \times \frac{L_n}{L_{total}} \).

Q4: What are typical inductance values used in circuits?
A: Inductance values range from microhenries (μH) for high-frequency applications to henries (H) for power applications.

Q5: How does frequency affect voltage division in inductive circuits?
A: In AC circuits, the inductive reactance (X_L = 2πfL) determines the voltage division, which varies with frequency.
