Presets

The op-amp is the fundamental building block of analog electronics. With negative feedback, its gain is set entirely by external resistors: an inverting amp gives −R2/R1, a non-inverting amp 1+R2/R1. An integrator uses a feedback capacitor to output the running integral of its input.

Configurationinverting
Gain-10.00×
Output-10.00 V
Statuslinear

Governing equation

Reading this result: Inverting gain is −R2/R1 = -10.00×: the output is a scaled, flipped copy of the input, set entirely by the resistor ratio.

Presets

Passive filters shape a signal's frequency content with resistors, capacitors, and inductors. An RC low-pass or high-pass has a cutoff at 1/(2πRC) where the response drops 3 dB; an RLC bandpass resonates at 1/(2π√(LC)) with sharpness set by its quality factor Q.

▶ Run in Python

Data Inspector

Cutoff fc1.6 kHz
Resonance f₀5.0 kHz
Quality factor Q0.32

Governing equation

Reading this result: Low-pass: signals below the 1.6 kHz corner pass, above it they roll off at 20 dB/decade, and the response is exactly 3 dB down right at the corner.

Sound Levels (dB SPL)Live

Controls

Presets

Decibels are logarithmic, so loudness does not add the way you expect: two identical sources are only 3 dB louder than one, and ten are 10 dB. Meanwhile a point source drops 6 dB every time the distance doubles (the inverse-square law). Sustained exposure above 85 dB risks hearing damage.

▶ Run in Python

Data Inspector

Combined at 1 m85.0 dB
At 4 m73.0 dB
Doubling sources+3 dB
Risksafe range

Governing equation

Reading this result: A single source falls from 85 dB to 73 dB across 4 m — about 6 dB lost each time the distance doubles.

About this simulation

The full Audio Amplifier tool models a fuse rating with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a fuse rating?
Open this page and use the live Audio Amplifier tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a fuse rating from your own measurements.
