Voltage/Current Divider implementation

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.

Computation or source lookup only

Input and validation requirements

Setting R1=0 and R2=0 makes the common denominator R1+R2 equal zero, producing undefined 0/0 results for both divider formulas. A robust instrument must reject this input.

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.

{
  "inputs": {
    "mode": "voltage_unloaded",
    "Vin_V": 12,
    "R1_kOhm": 1,
    "R2_kOhm": 2
  },
  "expected_outputs": {
    "Vout_V": 8
  },
  "working": "Vout = Vin·R2/(R1+R2) = 12·2/(1+2) = 24/3 = 8 V."
}
