Back to UnitDC Circuit & Transformer Simulation Lab
60fps interactive laboratory featuring a precision potentiometer null-balance experiment (investigating potential gradient and determining internal resistance) and an AC transformer power analyzer with real core lamination losses.
Marking a lesson complete represents finishing your study of the topic; it does not denote tested mastery.
Learning Objectives
- Adjust potentiometer wire parameters and jockey position to locate null-balance points with center-zero galvanometer telemetry.
- Determine unknown cell EMF and calculate internal resistance from shunted balance measurements.
- Simulate step-up and step-down AC transformer operation, observing oscilloscope waveforms and measuring efficiency under laminated vs solid cores.
