Cable Distance & Voltage Drop

This calculator helps you find the DC power output using voltage and electrical resistance values. It relies on a key formula from Ohm’s Law:

Power (P) = Voltage² (V²) ÷ Resistance (R)

This equation is widely used in electronics and electrical engineering to ensure circuits operate efficiently and safely. By understanding the power output, you can choose the right components and prevent overheating or equipment failure.

For example, with a 12V power source and 6Ī© resistance, the power is 24W. This quick calculation is essential when designing power supplies, LED systems, or battery-operated devices.

Whether you’re working on DIY electronics or industrial equipment, this tool ensures precise power estimates. Use it to optimize your circuit design and avoid energy loss or performance issues.
