Physics for IGCSE & O level - Magnets And Currents (Section 3 - No. 3)
What is the relationship between voltage and current in a step-up transformer?
Voltage and current both increase.
Voltage increases, current decreases.
Voltage decreases, current increases.
Voltage and current both decrease.
Explicació
In a step-up transformer, the voltage increases, and the current decreases (assuming ideal conditions and no losses).
