RLC Resonant Frequency Calculator When you have an electric field in one component (a capacitor) swapping energy with a magnetic field in another component (coils), … Read More

Physics doesn’t like rapid changes in current so there’s some waiting around required for an RL circuit which we’ll call RC for now, since I’m … Read More

There is one equation that serves as one practical design tool. The RC high pass cutoff frequency calculator makes a single equation a useful bench … Read More

In the analog world of electronics, we have a device called an RC low pass filter. It’s an electronic circuit that uses basic components: A … Read More

Enter your cap and resistor values into the RC time constant calculator and it will tell you what time constant (tau) are. But more importantly, … Read More

Here’s the calculator for computing how long a capacitor takes to charge up. Plug in some values and the tool will show you which volts … Read More

Capacitor add-in math seems like it would be easy; just plug numbers into a formula, done. But wiring them up one way or another make … Read More

If you’re accustomed to working with resistors, wiring capacitors in series seems…wrong. When you put resistors end to end, they adds up linearly. Capacitators? No … Read More

On paper, the Wheatstone bridge looks straightforward, but as always, good engineering matter. Essentially, it’s a pair of voltage dividers connected in parallel, but that … Read More
