Lei de Ohm e API de Circuitos
Matemática de circuitos eletrônicos como uma API. O endpoint ohms-law recebe quaisquer dois dos parâmetros tensão, corrente, resistência e potência e retorna todos os quatro (V = IR, P = VI = I²R = V²/R). O endpoint combine calcula o total de resistores, capacitores ou indutores ligados em série ou paralelo — resistores e indutores somam em série e combinam-se reciprocamente em paralelo, enquanto capacitores fazem o oposto. O endpoint voltage-divider calcula a tensão de saída de um divisor de dois resistores e a corrente através dele. O endpoint reactance calcula a reatância capacitiva (Xc = 1/2πfC), a reatância indutiva (XL = 2πfL), a frequência de ressonância LC e a constante de tempo RC ou RL. Tudo é calculado localmente com fórmulas exatas em unidades SI, portanto é instantâneo e privado. Ideal para design e educação em eletrônica, engenharia embarcada e de hardware, projetos de hobby e bancada, e ensino de física. Cálculo local puro — sem chave, sem serviço de terceiros, instantâneo. Ao vivo, nada armazenado. 5 endpoints. Isto é matemática de circuitos; para códigos de cores de resistores use uma API de resistores e para conversão geral de unidades use uma API de unidades.

RTD Pt100 Sensor API
RTD (Widerstands-Temperatur-Detektor) Sensor-Mathematik als API, lokal und deterministisch mit der IEC 60751 Callendar-Van Dusen Gleichung berechnet – die Widerstands-, Temperatur- und Toleranzzahlen, die ein Instrumentierungs- oder Steuerungsingenieur von einem Pt100 oder Pt1000 abliest. Der Widerstands-Endpunkt gibt den Sensorwiderstand aus der Temperatur: über 0 °C, R = R₀·(1 + A·T + B·T²) mit A = 3,9083×10⁻³ und B = −5,775×10⁻⁷; unter 0 °C fügt ein dritter Term C·(T−100)·T³ hinzu – ein Standard-Pt100 (100 Ω bei 0 °C) zeigt 138,51 Ω bei 100 °C und 80,31 Ω bei −50 °C, und ein Pt1000 ist das Zehnfache. Der Temperatur-Endpunkt kehrt dies um, um einen gemessenen Widerstand wieder in Temperatur umzuwandeln – analytisch über 0 °C, iterativ darunter – genau das, was ein Messumformer mit der Brückenablesung macht, und eine Erinnerung daran, dass eine 3- oder 4-Leiter-Verbindung den Leitungswiderstand aufhebt, sodass er nicht als zusätzliche Grad gelesen wird. Der Toleranz-Endpunkt gibt die IEC 60751 Genauigkeitsband in °C und Ω nach Klasse an – AA ±(0,10 + 0,0017·|T|), A ±(0,15 + 0,002·|T|), B ±(0,30 + 0,005·|T|), C ±(0,60 + 0,010·|T|) – der Fehler wächst mit der Entfernung von 0 °C. Alles wird lokal und deterministisch berechnet, daher ist es sofort und privat. Ideal für Instrumentierungs- und Steuerungssoftware, Datenlogger- und Messumformer-Firmware, Kalibrierungs- und industrielle IoT-Tools. Reine lokale Berechnung – kein Key, kein Drittanbieter-Dienst, sofort. 3 Compute-Endpunkte. Für NTC-Thermistoren verwenden Sie eine Thermistor-API; für Thermoelemente eine Thermoelement-API.

Voltage Divider API
Resistive voltage-divider circuit design as an API, computed locally and deterministically. The divide endpoint takes an input voltage and two resistors and returns the output voltage Vout = Vin·R2/(R1+R2), the current I = Vin/(R1+R2) that flows through the chain, and the power dissipated in each resistor and in total — a 12 V source with R1 = 1 kΩ and R2 = 2 kΩ gives 8 V at 4 mA. The loaded endpoint adds a load resistor across R2, computes the parallel combination R2′ = R2·RL/(R2+RL) and the loaded output Vout = Vin·R2′/(R1+R2′), and reports the droop in volts and percent against the unloaded value, the classic mistake when a divider feeds a real load. The resistor endpoint sizes the missing resistor for a target output — R2 = R1·Vout/(Vin−Vout) or R1 = R2·(Vin−Vout)/Vout — so you can pick parts for a reference or sensor-bias point. All quantities are volts, ohms, amps and watts. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, embedded, hardware, sensor-interfacing and EE-education app developers, reference-voltage and bias-network tools, and maker software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is the resistive divider; for a single Ohm’s-law relationship use an Ohm’s-law API and for RC/RL filters an RC-filter API.

RC Filter API
First-order RC and RL passive-filter design as an API, computed locally and deterministically. The lowpass and highpass endpoints take a resistor and capacitor (RC) or a resistor and inductor (RL) and return the −3 dB cutoff frequency (fc = 1/(2πRC) for RC, R/(2πL) for RL), the time constant (τ = RC or L/R) and the angular cutoff; pass a frequency as well and they add the magnitude response as a linear gain and in decibels and the phase shift in degrees — a 1 kΩ / 1 µF low-pass has fc ≈ 159.15 Hz, and right at the cutoff the gain is −3.01 dB with −45° phase for a low-pass or +45° for a high-pass. The component endpoint solves the missing one of fc, R and C from the other two (fc = 1/(2πRC)), so you can size a resistor or capacitor for a target cutoff. All quantities are SI: ohms, farads, henries and hertz. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, audio, embedded, signal-processing and EE-education app developers, filter-design and circuit-sizing tools, and maker software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is first-order single-pole filter design; for full RLC impedance and resonance use an impedance API and for stored capacitor energy a capacitor API.
