The input to output ratio of an isolation transformer is typically what?

An isolation transformer is designed to transfer electrical energy between two circuits while isolating them from each other. This isolation helps to protect against electrical shock and can also reduce electrical noise that might interfere with sensitive equipment.

The input to output ratio of an isolation transformer is typically 1:1. This means that the voltage input to the transformer is equal to the voltage output, assuming the transformer is operating under normal load conditions. The primary function of isolation transformers isn't to step voltage up or down but to provide a safe, isolated environment for electrical devices.

In circuit design, using a 1:1 ratio allows for a direct correlation in voltage levels, ensuring that the devices connected will receive the same voltage they output without any transformation. This characteristic is crucial in applications where grounding and safety are concerns, making the isolation transformer an essential component in many electrical systems.
