A transformer has 90 turns in the primary coil and 9 turns in the secondary coil. If
the output voltage is 6V, what is the input voltage?
60 Volts
You have a transformer with 50 turns in the primary coil. if you want to increase
the voltage from 5V to 6V, how many turns should be in the secondary coil?
60 Turns
A transformer has 150 turns in its primary coil and 50 turns in its secondary coil.
If the input voltage is 12V, What is the output Voltage?
4 Volts
A transformer has 1000 turns of wire in the primary coil and 50 turns in the
secondary coil. If the input voltage is 2400V, what is the output Voltage?
120V
A step down transformer reduces a 2400V current to 120V. If the primary coil has
500 turns of wire, how many turns of wire are there on the secondary coil?
25 turns
