1. What is the Current Divider?

The current divider rule is used to determine how current divides when it reaches a junction between parallel resistors in an electrical circuit.

2. How Does the Calculator Work?

The calculator uses the current divider formula:

Where:

• \( I_1 \) — Current through resistor R₁ (A)
• \( I_{total} \) — Total input current (A)
• \( R_1 \) — Resistance of first resistor (Ω)
• \( R_2 \) — Resistance of second resistor (Ω)

Explanation: The current divides inversely proportional to the resistances in parallel branches.

3. Importance of Current Division

Details: Understanding current division is crucial for circuit analysis, designing parallel circuits, and ensuring proper current distribution in electronic components.

4. Using the Calculator

Tips: Enter total current in amperes (A) and both resistor values in ohms (Ω). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this formula work for more than two resistors?
A: For multiple parallel resistors, first calculate equivalent resistance, then apply the divider rule to each branch.

Q2: What happens if one resistor is much larger than the other?
A: Most current will flow through the path of least resistance (smaller resistor).

Q3: Can I use this for AC circuits?
A: Yes, but with impedance (Z) instead of resistance (R) for AC analysis.

Q4: What if the resistors are equal?
A: The current will divide equally between the two branches.

Q5: Does this work for non-resistive loads?
A: For complex loads (like motors), additional factors like reactance must be considered.
