Is the statement true or false? A step down transformer has a voltage ratio of 1:4.

A step-down transformer is specifically designed to reduce voltage from the primary to the secondary side. The voltage ratio indicates how many times the primary voltage is greater than the secondary voltage, meaning if a transformer has a 1:4 voltage ratio, it would actually increase the voltage rather than decrease it. Hence, a step-down transformer cannot have a voltage ratio that results in a greater secondary voltage than the primary voltage.

In the context of the statement, if the voltage ratio were indeed 1:4, it would imply the secondary side has a voltage that is one-fourth of that on the primary side, which aligns with the definition of a step-down transformer. Thus, it is correct to say that the statement about a step-down transformer cannot be accurate in this case, leading to the conclusion that the statement is false.
