Description

⚡ Voltage Drop Calculator – Ensure Safe & Efficient Electrical Circuits

The Voltage Drop Calculator helps determine the voltage loss that occurs when current flows through a conductor due to resistance. This tool is essential in electrical engineering, wiring design, and power distribution systems to ensure proper performance and prevent energy loss or equipment damage.

📘 What It Calculates:

  • ✅ Voltage drop across a wire or cable

  • ✅ Percentage of voltage drop compared to supply voltage

  • ✅ Proper conductor size based on load and distance

  • ✅ Power loss due to resistance

💡 Features:

  • Supports copper and aluminum conductors

  • Works with single-phase and three-phase systems

  • Helps comply with NEC/IEC wiring standards

  • Improves safety and efficiency of circuits

👤 Who Should Use This:

  • 📌 Electricians designing wiring systems

  • 📌 Engineers working on power distribution

  • 📌 Students learning electrical circuits

  • 📌 Anyone installing long cable runs in homes or industries

✅ Pro Tip:

Keep voltage drop under 3% for branch circuits and 5% for feeders to ensure efficiency and safety.

🔗 Related Tools:

Voltage drop is the reduction in voltage as electric current flows through a conductor due to resistance.

Excessive voltage drop can cause equipment malfunction, energy loss, and overheating of wires.

Conductor material, wire length, cross-sectional area, load current, and system phase type.

V drop ​ =I×R, where 𝐼 I is current and 𝑅 R is resistance of the conductor.

Common standards recommend less than 3% for branch circuits and 5% for feeders.
