What is the current in the secondary coil in a transformer to increase from 9 V to 12 V, if the current in the primary coil is 4 A? How many turns are needed if the secondary coil have 125 turns?
Added by Dennis P.
Step 1
The voltage ratio in a transformer is equal to the ratio of the number of turns in the secondary coil to the number of turns in the primary coil. In this case, the secondary coil has 125 turns and the primary coil has an unknown number of turns. Therefore, the Show more…
