A. Consider a step-down transformer with 15 turns in the primary and 6 turns in the secondary windings.Calculate the input impedance of this transformer loaded to an 8 O resistor, assuming that series resistances of the windings are negligible.
B. A signal generator with an internal impedance of 50 O provides an open circuit voltage of 2 V. Find the voltage drop across a 50 ohm load connected to the generator. Repeat the calculations for an 8 O load. Find the electrical power delivered to the load in both cases.
C. Consider the generator from part B connected to a primary of the transformer from part A. The secondary is loaded to the same 8 ohm resistor. Find the voltage drop across the primary.
