**Question:**

Which of the following is a situation in which you might need a 1:1 transformer?

- O You want to step up the voltage but not the current
- O You want to step up the current but not the voltage
- O You want to fool the power company into giving you free electricity
- O You want to use one circuit to control another circuit that is electrically isolated from it

**Explanation:**

A 1:1 transformer is used primarily for electrical isolation rather than stepping up or down voltage or current. It provides a way to control one circuit with another while keeping them electrically isolated to ensure safety and prevent noise transfer.
