RMS Voltage Calculator is an online tool to help you quickly calculate the RMS (Root Mean Square) of common waveforms (e.g. sine wave, square wave, triangle wave, sawtooth wave). You can also use this tool backward and let it determine the peak voltage and peak-to-peak voltage if you know the RMS voltage.
Series and Parallel Capacitor Calculator allows you to quickly determine the total equivalent capacitance of up to ten capacitors connected in series or in parallel. This tool supports two modes: you can calculate the total equivalent capacitance or calculate the missing capacitor.
This calculator allows you to determine the total equivalent resistance of up to ten resistors connected in series or in parallel.
This tool allows you to determine which resistor you should use when you have a single LED or a number of the same color of LEDs in series. It displays resistor value, recommended resistor wattage as well as resistor color coding.
SMD Capacitor Code Calculator allows you to determine capacitance by the SMD (surface mount device) capacitor markings found on the device and to determine SMD capacitor markings by capacitance. It displays rated capacitance, capacitor tolerance and voltage.
SMD Inductor Code Calculator allows you to determine inductance of a SMD (surface mount device) inductor by the markings found on the device and to determine SMD inductor markings by inductance. It displays rated inductance and inductor tolerance.
A helpful tool for reading SMD (surface mount device) resistor markings found on the device. It displays rated resistance and resistor tolerance.
When the relay closes and opens, its contacts can be damaged by the resulting electric discharge arc. To protect them, you can use RC chains installed in parallel with the relay or load. You can calculate the parameters of the elements needed for this here by entering the general characteristics of the circuit.
This calculator allows you to determine signal parameters of a square pulse generator built on the basis of the popular 555 microcircuit which can operate in astable (self-oscillating) mode.
This calculator allows you to determine signal parameters of a square pulse generator built on the basis of the popular 555 microcircuit which can operate in monostable mode.
