Calculators

Calculates the induced electromotive force (EMF) in a circuit based on Faraday's Law of Induction. This law states that the EMF is proportional to the rate of change of magnetic flux through a circuit.

Calculates fluid pressure using the formula P = ρgh (density * gravity * depth) or based on force and area (P = F/A).

Converts between different units used in radio frequency engineering, including dBm, Watts, and Volts.

Calculates the focal length, object distance, or image distance for a thin lens using the thin lens equation: 1/f = 1/do + 1/di.

Calculates the total equivalent resistance of resistors connected end-to-end.

This calculator illustrates Heisenberg's Uncertainty Principle, which states that the more precisely the position of a particle is determined, the less precisely its momentum can be known, and vice versa.

Calculates the total equivalent resistance of resistors connected in parallel.

Calculates voltage, current, or resistance in an electrical circuit using Ohm's Law (V=IR).

Calculates the magnification power of a lens based on focal length or object/image distances.

Calculates the angular extent of a scene captured by a camera based on focal length and sensor size.
