Calculators

Determines the resistance and tolerance of a resistor based on its colored bands.

Calculates the recommended turbocharger size based on engine displacement, desired horsepower, and redline RPM.

Calculates the energy of a single photon based on its frequency or wavelength (E=hf or E=hc/λ).

This tool calculates cooling rates for different volumes of water using various cooling methods and visualizes the temperature change over time.

Estimates the maximum flight time for a drone based on battery capacity and power draw.

Calculates the wavelength associated with a moving particle, demonstrating wave-particle duality (λ = h/p).

Calculates the Root Mean Square (RMS) value of an AC voltage, representing its effective DC equivalent.

Calculates the shift in wavelength of light due to the Doppler effect or cosmological expansion.

Analyzes circuits containing resistors and capacitors, calculating time constants and charge/discharge behavior.

Calculates the mechanical advantage, output force, or output distance of a pulley system based on input parameters.
