Parallel resistors do not have the same current flowing through them. The current through each resistor depends on Example Current Calculation For a three resistor network (R1 = 10 Ω, …

Here we calculate the value of a resistor used in parallel with another known resistor to achieve a desired total effective resistance. Enter The tool will calculate the value of …

This tool calculates the time it takes to discharge a capacitor to a specified voltage level. The schematic consists of an RC network as shown in the title picture. As …

Calculate the time it takes to charge a capacitor to the level of the input voltage. Formula Vc = Vi (1-e-t/τ) where, time constant τ = RC, where R is …

This tool calculates the Dissipation Factor of a Capacitor. Enter: Formula D = ESR/|Xc| D = (2π*f*C*ESR) where, Background Dissipation Factor (DF) is a measure of a capacitor’s dielectric losses. …

A Bypass Capacitor is used to bypass high frequency signals and noise from power supplies. This prevents issues with Electromagnetic Interference (EMI). The picture below shows an example of bypass …

The crest factor of a waveform is given by the ratio of the peak to RMS amplitude level Enter Formula CF = Vpeak/VRMS Example Calculation If the peak value is …

This tool calculates the heat dissipated in a capacitor. Every capacitor has a finite amount of series resistance associated with it. This results in heat dissipation. The resulting temperature rise …

An ideal capacitor does not dissipate any power. However there is no such thing as an ideal cap. In reality, there’s an associated series resistance called the Equivalent Series Resistance …
