An isolation transformer is defined by having the same number of turns on primary and secondary.

An isolation transformer is defined by having the same number of turns on primary and secondary.

• A. Depends On Voltage Rating
• B. True
• C. False
• D. Not Related To Turns

Answer: (B)

Isolation is the key idea here: an isolation transformer provides galvanic separation between the input and output windings, so there’s no direct electrical path for current to flow from one side to the other. The typical way to achieve that clean separation without changing the voltage level is to use a 1:1 turns ratio, meaning the primary and secondary have the same number of turns. With equal turns, the secondary voltage roughly matches the primary (aside from losses), and power is transferred magnetically while keeping the two sides electrically isolated. That’s why this statement is considered true in standard practice. It’s worth noting that you can have isolation with different turns ratios in some designs, but the common, straightforward isolation transformer is 1:1, which is what this item tests.
