A. primary turns to secondary turns
B. secondary current to primary current
C. secondary induced e.m.f. to primary induced e.m.f.
D. secondary terminal voltage to primary applied voltage
This Answer Is D
The voltage transformation ratio of a transformer is the ratio of the secondary voltage to the primary voltage. This ratio is determined by the number of turns in the primary and secondary windings. The transformer turns ratio is defined as the number of turns in the secondary divided by the number of turns in the primary.
The voltage ratio (VR) is the ratio of primary voltage to secondary voltage. It is important to note that the transformation ratio is determined by the ratio of primary turns to secondary turns. Knowing this ratio helps determine the output voltage from a transformer and is used in many electrical applications.
