# Capacitor Energy & Charge Calculator implementation

A source-bound implementation contract for Capacitor Energy & Charge Calculator; deployment and executable qualification remain separate.

Status: **VERIFIED_CLEAN**Lifecycle: **implementation-contract**

## Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

**Record owner**: Guth Instruments

**Lifecycle**: verified-clean

**Evidence ID**: t5-101

**Effect**: Computation or source lookup only

## Input and validation requirements

Extreme finite inputs overflow JavaScript arithmetic to Infinity for both outputs. Additionally, the specification claims RC charge time but supplies no resistance, time constant, or RC-time formula, so that output cannot be computed from the stated inputs and formulas.

## Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

## Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.
