An autotransformer steps 120VAC up to 125VAC. Primary current flow is 18A. How much neutral current flow (in Amperes) does this transformer have?
Added by Lidia O.
Step 1
The turns ratio of an autotransformer is given by the ratio of the voltage difference between the primary and secondary windings. In this case, the voltage is stepped up from 120VAC to 125VAC. Therefore, the turns ratio can be calculated as follows: Turns ratio = Show more…
