Torque, is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as ... more

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, ... more
