Which of the following principles is transformer based on?
A transformer is basically an electromagnetic static equipment based on the principle of Faraday’s law of electromagnetic induction.
What are the parameters of transformer could be determined in an open circuit test?
The open circuit test is performed to determine the no load losses or core losses as well as the turns ratio, no load currents, magnetizing components and core loss components of the transformer.
What is the working principle of a transformer on load?
Transformer operation is based on the principle of mutual induction, that is, the changing current in the primary winding produces the changing flux in both windings, causing a back EMF in the primary winding and an induced voltage in the secondary winding, which is in fact the same as the induced EMF.
Which of the following is the transformer principle Mcq?
A Transformer is used to convert low voltage (or high current) to high voltage (or low current) and high voltage to low voltage. It works on the principle of mutual induction.
