To solve the problem regarding the frequency of the current in the secondary coil of a step-up transformer, we can follow these steps: ### Step 1: Understand the Function of a Transformer A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction. It can change the voltage and current levels but does not change the frequency of the alternating current. **Hint:** Remember that a transformer changes voltage and current levels but keeps the frequency constant. ### Step 2: Identify the Given Information ...
