I have a transformer. The only data I know about this transformer is as below:
- Conversion ratio is 220V:12V
- Power rating is 4VA
- Rated frequency is 50Hz
I want to connect a heater (resistor) across the secondary windings of this transformer, so that it will drain maximum power from the transformer.
I know that, according to the Maximum Power Transfer Theorem, impedance of the load must be complex conjugate of impedance of the source. But how do I calculated internal impedance of a transformer?![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Can you please suggest me a method that will either calculate internal impedance of the transformer, or the value of the load impedance which would drain maximum power from the transformer?
