## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ac-series-rlc-circuit-calculator-740b070b
```

Example prompt: Calculate the impedance, phase angle, resonant frequency, Q-factor, and bandwidth for a series RLC circuit with 10 ohms resistance, 50 millihenries inductance, and 100 microfarads capacitance driven at 60 Hz with 120 V RMS.

## When to prefer this

Use this endpoint when you need a fast, on-demand numerical solution for a series R-L-C AC circuit — especially when you need multiple computed quantities (impedance, Q, bandwidth, resonant frequency, component voltages) in a single call. Prefer this over manual calculation or general-purpose math tools when working inside an automated agent workflow that needs structured JSON output. It is specifically suited for series (not parallel) RLC configurations at a single frequency point.

## Known failure modes

- Missing required fields (resistanceOhm or frequencyHz) returns a validation error
- Zero resistance with only L or C may produce division-by-zero or infinite Q
- Omitting voltage means current and power outputs will be null
- Negative or physically impossible component values may return errors or nonsensical results
- Network or payment (x402) failure results in no response

## How this service works

Series R, L, C impedance, phase angle, current, resonant frequency, Q and bandwidth at a given frequency.

## Output

Returns a JSON object containing: impedance in ohms, phase angle in degrees, current in amps, inductive and capacitive reactance, net reactance, resonant frequency in Hz, quality factor (Q), bandwidth in Hz, power factor, real power in watts, apparent power in VA, and individual voltages across the resistor, inductor, and capacitor — all derived from the supplied R, L, C, frequency, and optional source voltage values.
