In exchange, the muscle package requires a massive electrical input.

There is also an importance for the electrolyser stacks to be able to accept a fluctuating electrical input, such as that found with renewable energy.

Its energy performance requirement is usually stated in terms of minimum efficacy (light output per electrical input).

In fact, at 2500 C, electrical input is unnecessary because water breaks down to hydrogen and oxygen through thermolysis.

The use of a pacemaker would ensure that the heart receives a constant rhythmic electrical input that never changes in frequency.

Output: Rotor assumes position determined by electrical input supplied.

A microwave oven converts only part of its electrical input into microwave energy.

"Once a current starts flowing through, it just keeps going with no further electrical input."

For analogue transmission, the light output must vary in linear fashion with the electrical inputs.

In a small scale it requires no electrical input.
