Task id12066
The number of turns of the secondary winding of the transformer is twice the number of turns of the primary winding. The active resistance of the primary winding is 20 Ohms, and its inductive reactance is 200 Ohms. An alternating voltage of 100 V is applied to the primary winding. Determine the voltage on the secondary winding in no-load mode. How will the voltage on the secondary winding change if the transformer core is replaced with another of the same size, but made of a material with a magnetic permeability 10 times less? Neglect flux leakage and core losses.
