Answer:
3 volts
Explanation:
Number of turns in primary coil = = 100
Number of turns in secondary coil = = 200
Voltage across primary coil = = 1.5 volts
Voltage across secondary coil = = ?
In a transformer, the ratio of number of turns of primary to secondary coil is equal to the ratio of the respective voltages i.e.
Using the given values, we get:
Thus, the voltage measure across secondary coil would be 3 volts
