EEE :: Transformers
- Short circuit test on transformers is conducted to determine
- In a certain transformer, the input power to the primary is 120 W. If 8.5 W are lost to the winding resistance, what is the output power to the load, neglecting any other issues?
- Which of the following acts as a protection against high voltage surges due to lightning and switching?
- The power factor of an induction motor under no-load conditions will be closer to
- Auto-transformer makes effective saving on copper and copper losses, when its transformation ratio is
- The path of a magnetic flux in a transformer should have
- The path of the magnetic flux in transformer should have
- The permissible flux density in case of cold rolled grain oriented steel is around
- No-load current of a transformer has
- In a step-down transformer, there is a change of 15 A in the load current. This results in change of supply current of
