What does a step-up transformer step up—voltage, current, or energy?
To Explain: The type of transformation (voltage, current or energy) done by step − up transformer.
Explanation of Solution
Introduction:
In a step-up transformer, the turn’s number in primary coil is less than the number of turns in secondary coil.
Voltage through a coil is directly proportional to number of turns in a coil. As number of turns is more in secondary coil, output voltage is more than input voltage. It means voltage is stepped up.
Conclusion:
Step − up transformer is used to step up voltage.
