a Thermocouple
Thermocouple
A generator. It uses the heat energy from burning gasoline or a similar fuel.
A thermocouple does this, but a turbine does also.
A photocell or photoelectric cell converts sunlight into electrical energy.
It is a thermocouple that converts thermal energy into electrical energy through what is called the thermoelectric effect.
A photocell converts light energy (radiant electromagnetic energy to be precise) into electrical energy. A thermocouple can convert heat into electrical energy. The radiant em conversion yields much more energy than a heat conversion.
A thermocouple converts thermal energy into electrical energy through the thermoelectric effect. Thermocouples are self powered and can measure a wide range of temperatures.
I might be wrong on this one, but I believe it is either a cell or a photocell. A cell would be correct, a photocell converts light energy into electrical energy.
Light heats a photocell, and the difference in temperature creates an electric current(:
A thermocouple uses the thermoelectric effect to do what it does. Thermal energy (heat) is converted into a difference of potential, which is electric (electromagnetic) energy.
