<u>Answer:</u>
150 volts
<u>Explanation:</u>
For a transformer which is designed and operated properly, the ratio of primary to secondary coil voltages is proportional to the ratio of primary to secondary coil winding turns.
Here in this case, we have 300 primary coil turns and 600 secondary coil turns which is the double of primary coil turns so the secondary voltage is the double of the primary voltage.
Input voltage = 2 x 75 = 150 volts
