A transformer has an input of 6 VV and an output of 180 VV .
If the input is changed to 24 VV , find what would be the output.

I have solved the question using the relation of transformer(constant power).
If you have any doubts please comment and I will clarify your doubt...
120 volts and 5 amps is input into a transformer. it has 5000 turns on the primary side and 500 turns on the output side. what is the voltage and current output assuming 100% efficiency?
2. The ac adapter for a laptop computer contains a transformer. The input of the adapter is the 120 volts from the ac wall outlet. The output from the transformer is 20 volts. What is the turns ratio of the transformer? a. 100 b. This cannot be determined without knowing how many turns one of the coils in the transformer has. c. 0.17 d. 6
The output rms voltage of a 480 W transformer is 240 V and the input rms current is 0.4 A. The primary coil has 200 turns, how many turns does the secondary could have?

In a step-down transformer, is the ratio of the number of input coils to the number of output coils greater than for a step-up transformer? Explain your reasoning. a. Yes, for a step-down transformer the output voltage is more than the input voltage. b. No, for a step-down transformer the input voltage is more than the output voltage.
A transformer has 500 turns in the primary and 50 turns in the secondary. If the input voltage is 120V, what is the output voltage? Answer: V If the transformer has an efficiency of 92%, what is the output current if the input current at 120V is 0.50A? Answer: А
