Op-Amp Gain API
Operational-amplifier gain and bandwidth maths as an API, computed locally and deterministically. The gain endpoint computes the closed-loop gain of an inverting (Av = −Rf/Rin) or non-inverting (Av = 1 + Rf/Rin) amplifier from the feedback and input resistors, gives the gain in decibels (20·log₁₀|Av|) and the output voltage for an input, and solves the feedback resistor needed for a target gain. The summing endpoint computes the output of an inverting summing (adder) amplifier, Vout = −Rf·Σ(Vi/Ri), from any number of weighted inputs — the basis of analogue mixers and digital-to-analogue converters. The bandwidth endpoint applies the gain-bandwidth product, GBW = closed-loop gain × bandwidth, and solves any of the three (a 1 MHz op-amp at a gain of 10 has a 100 kHz bandwidth), and computes the full-power bandwidth from the slew rate and the peak output voltage, f = slew_rate/(2π·Vpeak). Everything is computed locally and deterministically, so it is instant and private. Ideal for analogue-electronics and circuit-design tools, amplifier, filter and sensor-conditioning design, audio and instrumentation apps, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is op-amp amplifier design; for Ohm's law, reactance and resonance use an Ohm's-law API.

BJT Transistor API
Bipolar-junction-transistor (BJT) circuit maths as an API, computed locally and deterministically. The currents endpoint relates the three terminal currents through the DC current gain β (hFE): the collector current Ic = β·Ib, the emitter current Ie = (β+1)·Ib and the common-base gain α = β/(β+1) ≈ 1, from β and any one current. The bias endpoint analyses the operating point of the classic voltage-divider bias network — from the supply voltage, the two divider resistors, the collector and emitter resistors, β and the base-emitter drop it computes the Thévenin equivalent (Vth = Vcc·R2/(R1+R2), Rth = R1‖R2), the base current Ib = (Vth − Vbe)/(Rth + (β+1)·Re), the collector and emitter currents, the collector-emitter voltage Vce and the node voltages, and classifies the operating region as cutoff, active or saturation. The power endpoint computes the transistor's power dissipation, Pd ≈ Vce·Ic (plus Vbe·Ib), to check it against the rated maximum. Currents are in amperes, resistances in ohms and voltages in volts, with Vbe defaulting to 0.7 V for silicon. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, amplifier-design, embedded and hobbyist app developers, biasing and operating-point tools, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is BJT biasing; for op-amp circuits use an op-amp API and for an LED series resistor an LED-resistor API.

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.
