Physics
Ohm's Law Calculator
Compute voltage across a component using Ohm’s Law, V = I·R, given the current flowing through it and its resistance. The most fundamental relationship in electronics, used in every circuit design from LED dropper-resistors to industrial power systems.
Fill in the required fields to see your result.
Physics
Force Calculator (Newton's Second Law)
Calculate the net force on an object from its mass and acceleration using Newton’s Second Law, F = m·a. The cornerstone of classical mechanics, used everywhere from sizing motors to estimating brake forces to predicting how hard a ball will hit the ground.
