Answer :
Final answer:
The turns ratio of the transformer is 0.2. When the primary winding is connected to a 1200V rms source through a 60∠−30∘ Ω impedance, the primary current is I1 = 19.77 ∠(27.759)A and the secondary current is I2 = 98.876 ∠(27.759)A.
Explanation:
In this scenario, we are dealing with a transformer which has a voltage ratio of 1200/240 or 5:1. This means that the turns ratio, which is the ratio of the number of turns in the primary coil to the number of turns in the secondary coil, is also 5:1, or simply 0.2 as given in the question.
So, turns ratio n = 0.2.
Next, we want to calculate the primary and secondary current. If the primary winding is connected to a 1200V rms source through an impedance of 60∠−30∘ Ω, we can calculate the current using Ohm's law (I = V/R).
So, the primary current I1 = 19.77 ∠(27.759)A, and the secondary current I2 = 98.876 ∠(27.759)A. Here, the angle represents the phase difference between the current and voltage.
