Question

If a transformer and a system have the same X/R ratio, what does that mean?

A. The transformer and the system have the same resistance.
B. The transformer and the system have the same reactance.
C. The transformer and the system have the same power factor.
D. The transformer and the system have the same impedance.

Answer 1

When a transformer and a system have the same X/R ratio, it means that they have the same impedance.

Step-by-step explanation:

When a transformer and a system have the same X/R ratio, it means that the transformer and the system have the same impedance. Impedance is the combined effect of resistance (R), inductive reactance (XL), and capacitive reactance (XC) in an AC circuit. It is analogous to resistance in a DC circuit and is measured in ohms.
