Current Divider

This tool helps you calculate equivalent temperature values across multiple commonly used temperature scales with ease. The Kelvin and Rankine scales serve as absolute counterparts to the Celsius and Fahrenheit scales, respectively. These absolute scales start at zero, representing the theoretical minimum temperature possible. On the other hand, the zero points for Celsius and Fahrenheit were established based on observable physical phenomena, such as the freezing point of water. Use this tool for accurate temperature conversions and gain a deeper understanding of the relationships between these scales.

Understanding Current Division

The current divider rule helps in calculating the current flowing through each branch of a parallel circuit. This is a fundamental principle in electrical engineering, especially when dealing with circuits involving multiple resistors.

Formula for Current Division

For two resistors R₁ and R₂ in parallel:

I₁ = (R₂ / (R₁ + R₂)) × I_total

I₂ = (R₁ / (R₁ + R₂)) × I_total

Key Concepts

Total Resistance in Parallel Circuits:
The reciprocal of the total resistance ( R_t ) in a parallel circuit is the sum of the reciprocals of the individual resistances:

1 / R_t = 1 / R₁ + 1 / R₂ + ...
Proportional Current Flow:
The current in each branch is inversely proportional to the resistance of that branch. Higher resistance means lower current, and vice versa.
Practical Applications:
- Designing circuit breakers.

- Optimizing power distribution in circuits.

- Understanding load balancing in electrical systems.

Tips for Using the Calculator

Ensure all resistance values are positive and not zero.
Use consistent units (e.g., Ohms, mA, A).
The tool will automatically calculate the current through each resistor and display results in your preferred unit.
