It seems like there's a bit of confusion in your question. Efficiency is a concept that is typically applied to systems or devices, like engines or power plants, not to a quantity like voltage.

However, if you're referring to the efficiency of a system that involves voltage, such as an electrical circuit or a power supply, then the efficiency would be calculated as the ratio of useful power output to the total power input. This is often expressed as a percentage.

Here's a step-by-step guide on how you might calculate this:

1. Determine the total power input. This can often be found on the specifications of the device or system you're looking at. For an electrical system, power (P) is calculated as the voltage (V) multiplied by the current (I), or P = V * I.

2. Determine the useful power output. This is the amount of power that is actually being used to perform the useful work. This can often be more difficult to determine, as it may require knowledge of the system's internals.

3. Divide the useful power output by the total power input, then multiply by 100 to get the efficiency as a percentage.

Remember, efficiency is always less than or equal to 100% due to the laws of thermodynamics - some energy is always lost as waste heat in any real-world system.
