Introduction to some calculation tools:

Resistance, capacitance and inductance calculators

Ohm's Law Calculator: Ohm's law calculates the relationship between voltage, current and resistance.

Capacitor Calculator: Calculates the total capacitance of different connections (series or parallel).

Inductor Calculator: Calculates the inductance value of an inductor, applicable to series and parallel inductance combinations.

RC, RL, LC and RLC circuit calculators

RC circuit time constant calculator: Calculates the time constant of a resistor-capacitor circuit, used for filter circuits or signal delays.

RL and LC Circuit Calculator: Calculates resonant frequency in resistor-inductor or inductor-capacitor circuits.

RLC Circuit Resonant Frequency Calculator

Used to calculate resonant frequency and damping factor for series or parallel RLC circuits.

Filter Design Tool

Used to calculate low-pass, high-pass, band-pass, and band-stop filters.

Battery Calculator

Calculates battery life, especially useful for low-power device designs.

4/5/6 Band Resistor Color Code Calculator

Used to decode information for color-band axial lead resistors. Select the number of bands and then the color to determine the resistor's value and tolerance
