Calculators
Create and discover interactive calculators for various scenarios and measurements.
Lever Calculator
Analyzes forces and distances in a lever system based on the fulcrum position.
Impedance Matching Calculator
Calculates the component values (e.g., in L-networks) needed to match impedances for maximum power transfer.
Electrical Power Calculator
Calculates electrical power using voltage, current, and resistance, based on the formulas P=VI, P=I²R, and P=V²/R.
Angular Displacement Calculator
Calculates the change in angular position of a rotating object.
Wavelength Calculator
Calculates the spatial period of a wave (distance over which the shape repeats) based on speed and frequency (λ = v/f).
Voltage Divider Calculator
Calculates the output voltage from a simple circuit that divides a source voltage across two resistors.
Angular Momentum Calculator
Calculates the rotational equivalent of linear momentum using the formula L = Iω or L = r x p, where L is angular momentum, I is the moment of inertia, ω is the angular velocity, r is the radius, and p is the linear momentum.
Battery Life Calculator
Estimates how long a battery will last based on its capacity and the device's power consumption.
Relativistic Kinetic Energy Calculator
Calculates the kinetic energy of an object moving at relativistic speeds, considering the effects of special relativity.
Reynolds Number Calculator
Calculates the Reynolds number, a dimensionless quantity that helps predict fluid flow patterns (laminar vs. turbulent).
