| Jul 14, 2023 at 15:04 | comment | added | Andy aka | A change in flux induces a voltage and not a current. In case you weren't aware, this site isn't a forum where a potentially endless stream of questions and answers are raised and expected to be answer so, given that you don't appear to be 100% up on transformers, I'm encouraging you to start a new formal question on the subject. It will also draw in other users to make a contribution. | |
| Jul 14, 2023 at 15:01 | comment | added | Alzeno Doe | Yep , wouldn't the magnetic flux due to the primary coil gradually decrease from T/4 to T/2 as current falls to zero? Then we are getting, a negative flux change. and negative flux change should induce opposite current now? , I'm kinda embarrassed but I need clarity to myself and sorry for interrupting you ☺️ | |
| Jul 14, 2023 at 13:18 | comment | added | Andy aka | Between 0 and T/2 you get the positive voltage waveform of a sinewave. Between 0 and T/4 it is rising up to a peak and, from T/4 to T/2 it starts at the peak and falls down to zero. All the time, a positive current is produced in the resistive load. @AlzenoDoe if we are done here, please take note of this: What should I do when someone answers my question.

| Jul 14, 2023 at 11:11 | comment | added | Alzeno Doe | can you pls clarify what happens during the 0 to T/4 vs T/4 to T/2 ? | |
| Jul 14, 2023 at 11:08 | comment | added | Andy aka | The current in the secondary is due to the secondary induced voltage and the load connected to the secondary and, nothing else (basic ohms law). The secondary induced voltage is due to primary voltage and turns ratio. You can't suddenly create an opposite current at the peak of the voltage waveform that is driving a load resistor. | |
| Jul 14, 2023 at 11:05 | comment | added | Alzeno Doe | so you mean increase or decrease in flux due to the primary transformer will not change current !? but how does the faraday's law and lenz's law holds here? according to law if you increase magnetic flux ,the current will be opposite to when you decrease the magnetic flux. | |
