Voltage Drop Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a Voltage Drop Calculator?
A Voltage Drop Calculator is a tool used to determine the voltage drop across a circuit based on various parameters such as the length of the wire, the current flowing through it, and the material of the conductor. In South Africa, this calculator is essential for ensuring that electrical systems function properly and safely, especially in buildings, industrial settings, and automotive applications.
How to Calculate Voltage Drop Manually
The formula for calculating voltage drop is as follows:
Voltage Drop (VD) = (2 * K * I * L) / A
Where:
- Voltage Drop (VD) is the drop in voltage in volts
- K is the conductor’s constant
- I is the current in amperes
- L is the length of the wire in meters
- A is the area of the conductor in square millimeters
For example, let’s consider a scenario in South Africa where you have a 50-meter long copper wire with a current of 10A flowing through it. The area of the conductor is 6mm², and the constant K for copper is 12.9. Plugging these values into the formula will give you the voltage drop across the wire.
