Educational use

Results and availability

Models use floating-point arithmetic, display rounding and disclosed assumptions. Simplified rectifier and filter models omit important physical effects. Regulator results are conditional on supplied input and device assumptions. Software errors, interruptions and changing source documents remain possible; no particular suitability or continuous availability is guaranteed.
