Calculate voltage drop in electrical circuits with ease using our tool
Voltage drop is a critical factor in electrical engineering, representing the reduction in voltage across a component or circuit due to resistance. It's essential for designing efficient electrical systems.
The voltage drop calculator helps you determine the voltage drop across a conductor based on its resistance, current, and length. This is crucial for ensuring that electrical devices receive the appropriate voltage to function correctly.
Our calculator uses the formula V = I × R, where V is the voltage drop, I is the current, and R is the resistance of the conductor. The resistance can be calculated using the formula R = ρ × (L/A), where ρ is the resistivity of the material, L is the length, and A is the cross-sectional area.
