Physics for IGCSE & O level - Magnets And Currents (Section 7 - No. 41)
If a transformer has a turns ratio of 1:10, what will happen to the current?
It will increase by a factor of 10
It will decrease by a factor of 10
It will remain the same
It will depend on the voltage
Erläuterung
The current is inversely proportional to the turns ratio, so it will decrease.
