A transformer with a turns ratio (secondary/primary) of 1: 18 is used to step down the voltage from a $120-\mathrm{V}$ wall socket to be used in a battery recharging unit. What is the voltage supplied to the recharger?
Added by Lisa D.
Step 1
The turns ratio is given as 1:18, which means that for every 1 volt applied to the primary coil, 18 volts are induced in the secondary coil. Show more…
