The power and current ratios of a transformer are dependent on the fact that power delivered to the secondary is always equal to the power delivered to the primary minus the losses of the transformer. This will always be true, regardless of the number of secondary windings. Using the law of power and current, it can be stated that current through the transformer is the inverse of the voltage or turns ratio, with power remaining the same or less, regardless of the number of secondaries. What is the relationship between the power and current ratios of a transformer?
1) The power and current ratios of a transformer are directly proportional
2) The power and current ratios of a transformer are inversely proportional
3) The power and current ratios of a transformer are not related
4) The power and current ratios of a transformer depend on the number of secondary windings
