Current Divider Calculator
The Current Divider Calculator is a specialized tool designed to simplify the process of determining how electric current divides among parallel branches in a circuit. It is particularly useful for engineers, students, and hobbyists working with parallel resistor configurations, ensuring accurate calculations without manual computations.
Key Features
- Input Flexibility: Accepts resistor values and total current to compute branch currents.
- Real-Time Results: Instantly displays the current flowing through each parallel resistor.
- Unit Support: Works with ohms (Ω), kilo-ohms (kΩ), and milliamperes (mA) for convenience.
- Error Handling: Validates inputs to prevent invalid or unrealistic values.
How to Use
To use the calculator, follow these steps:
- Enter the total current supplied to the parallel circuit (e.g., 10 mA).
- Input the resistance values of each parallel branch (e.g., R1 = 100 Ω, R2 = 200 Ω).
- Click Calculate to see the current division results for each resistor.
Example Calculation
| Parameter | Value |
|---|---|
| Total Current (Itotal) | 12 mA |
| Resistor 1 (R1) | 500 Ω |
| Resistor 2 (R2) | 1000 Ω |
| Current through R1 (I1) | 8 mA |
| Current through R2 (I2) | 4 mA |
Note: The calculator applies the formula In = (Itotal × Rtotal) / Rn, where Rtotal is the equivalent parallel resistance.
Applications
This tool is invaluable for:
- Designing circuits with precise current distribution.
- Troubleshooting parallel circuits in labs or real-world projects.
- Teaching Ohm's Law and Kirchhoff's Current Law principles.
