... Note that in Fig. 7, the currents I1 and I2 are the currents through the respective windings, and the voltage E1 and E2, are the voltages across the respective windings. The transformer iron core and windings are exactly as in the two winding case, and so all standard relations between winding curr ...

Current Meter Guard/Ground Connections
... The Guard Return mode is used to measure the leakage current through the test object only and not any other stray leakage currents. This permits the accurate reading of leakage currents through only the insulation area desired. When using the Guard Return mode, so long as the low end of the load, th ...

High-performance differential VCO based on armstrong oscillator
... The operational principle of the circuit is based on the classic Barkhausen criterion where the cross-connected differential pair provides the negative resistance. The bias of transistors Q1 and Q2 is fed from the center-tap of a secondary coil of the transformer. The power supply is coupled to the ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
