What principle do the Transformers work
Describe in brief on what principle do the Transformers work?
Expert
The transformer is a static device which transfers electrical energy from one circuit to the other via inductively coupled conductors-the transformer's coils. Varying current in the first or primary winding makes a varying magnetic flux in the transformer's core and therefore a varying magnetic field via the secondary winding. This varying magnetic-field induces a varying electromotive force (EMF) or ‘voltage’ in the secondary winding. This effect is termed as mutual induction.

This homework deal with power electronics especially buck converters. It is not hard to solve but because I have no time to solve it I want you to help me.
A simple transistor buffer is needed to drive a length coaxial cable containing a capacitance of 100pF per meter length. The whole steady-state power dissipation of the buffer should not exceed 250mW and the propagation delay of a pulse transmitted along the cable sho
