# Transformers

### Explanation of question 6

A transformer is rated at 50VA. This means that

1. the load in the primary must be 50VA
2. the load in the secondary must be 50VA
3. the primary load must exceed 50VA
4. neither the primary nor secondary loads should exceed 50VA

The answer is :- 4

The VA rating of a transformer is the maximum power that can be safely handled by the transformer. Since power is the same on both sides of the transformer, neither primary nor secondary windings can safely supply a load greater than 50VA (50W)
