PLEASE SO PART C, THANK YOU WILL RATE.
A single-phase transformer with a 5:1 turns ratio is connected to a 600 V voltage source on the primary side, and a 5 Ω resistor on the secondary. A current of 22 amps of current is measured to flow through the 5 Ω resistor on the secondary side. The real power flowing into the transformer primary is measured at 2500 W. You can neglect Lm and Rc (the magnetizing inductance and core...

1. In class we derived how a transformer can up or downregulate
the voltage in an electrical circuit with an alternating
current.
(a) Use the conservation of energy to deduce how the currents I1
and I2 must be related if you know the ratio of ε1/ε2 (for the
purpose of calculating the power delivered by a circuit ignore any
complications due to the fact that I(t) and ε(t) are
time-varying).
