Which of the following is not a transducer?1 pointMoving coil generatorPhotovoltaicPhotoconductiveElectrooculogram

The option that is not a transducer among the given options is Electrooculogram.

A transducer is a device that converts one form of energy to another.

1. Moving coil generator: This is a transducer. It converts mechanical energy into electrical energy.
2. Photovoltaic: This is also a transducer. It converts light energy into electrical energy.
3. Photoconductive: This is a transducer as well. It changes its electrical resistance based on the amount of light it is exposed to.

However,

4. Electrooculogram: This is not a transducer. It is a test that measures the electrical activity of the eye and the oculomotor system. It does not convert one form of energy into another.
