Engineering Calculators

Electronics

BJT Feedback Amplifiers
Calculates feedback amplifier resistors, gain and impedances.
Carver LC Tester
Calibrates a Carver-style LC Tester jig and gives Inductances and Capacitance.
Coil Distributed Capacitance
Estimates the true inductance and distributed capacitance of an inductor from two resonance measurements.
LCR Resonance
Calculates LC resonance and optionally Q
Ring Inductance
Calculates inductance of a single turn of conductor.
Solenoid Inductance
Calculates inductance of a solenoid.

Circumference Divider
Calculates the length of a chord that divides a circle circumference into an integer number of parts.
Cone Generator
Calculates the diameter and sector angle of a planar conical development.
