Question

Why current reduces with increase in voltage in the case of Transformers.

Answer 1

Please do not answer theoretically like P=vi as v increases I reduces. But answer me in terms of Electrons or charge something like that.
Im looking for some practical explanation.

Answer 2

Power is a formula VxI, or using Ohms law to replace the V, Power = IxIxR, and the power lost in the power line is then just current and resistance. Reduce either and you reduce the power loss - so if you can reduce the current since this is a squared function.

Since power also equals VxI, reduce I and you have to increase V to get the same amount of power to flow through the system. So to reduce I, make the volts high, and since I is now low the losses in the power line are low as well.

Answer 3

@mujjazi thank you so much for your explanation which is actually the concept of HVDC. But this is not for which im looking for.
I want to know how electrons or charge or nucleus behaviour is happening in this process of increasing voltage by which current is reducing.

Answer 4

In the case of transformers, it is not about electrons or charges or nucleus behavior, it is about magnetic flux and the ratio of turns between primary and secondary windings

Answer 5

Transformers rely on the principle of magnetic induction, Faraday's law. Magnetic induction is a universal principle so should be valid on any scale, so also on atomic/electronic level. Every electric charge that moves causes a magnetic induction and creates thus a magnetic field around itself (that counters its moving force) and that field has a certain energy in itself. If this magnetic field is changing the energy buildup also changes. This changing magnetic field and the induction law drives the working principle of tranformers.
The energy in a transformer can be in the form of high voltage and low electric current or low voltage high electric current, since voltage (U) and electric current (I) together are the power (P) that is transferred from one side of the transformer to the other in the form P = U.I (the . stands for multiplication). In practice the power goes through the transformer with some losses in the transformer core and wire materials.
A transformer is called that because it changes the value of U (Volt) and I (Ampere).

P1 (input power) = P2 (output power) if power losses are neglectable.
