This is essentially a thermocouple, which is a junction between two different metals. These are used to measure temperature in some piece of equipment where you can't introduce a thermometer, and can provide a remote indication of temperature. If a large number of thermocouples are assembled you can get enough current to operate small devices, this assembly is called a thermopile.

∙ 6y agoIt is possible in principle to convert heat into electricity (or some other type of useful energy). But you always need a temperature *difference* and it is *not* possible to convert *all* heat into electricity. For more details, you may want to do some reading on *Carnot engines*.

Is thermocouple a sensor or a transducer?
Transducer since it transform heat into electrical voltage
How does a transducer measure current?
a transducer is a device that converts one form of energy to electric energy there are different types of transducers like mic is an acoustic transducer that converts sound energy to electrical energy...resistance changing transducers,inductance changing transducers capacitive type transducer ....change their values in accordance with an analog quantity to b measured like temp etc....this change produces porportional current or voltage which is basically proportional electrical energyTransducer, in electronics, a device that converts electric energy into some other form of energy, or vice versa. Transducers are used in sound systems, in video equipment and in many measuring devices. A transducer used in a measuring device produces an electric current proportional to the strength or intensity of the physical quantity-such as heat, light, or mechanical stress-to which the transducer is subjected. Piezoelectric crystals (crystals that produce an electric current when deformed) and photoelectric cells are transducers; so are loudspeakers, which produce sound from electric energy.
What elements in a curcuit can change eletrcical energy into other forms of energy?
Resistance converts electrical energy into other forms of energy, such as light, heat sound, motion, and magnetic effects.
What is difference between transducer and transmitter?
today the general rule of thumb is that if the pressure sensor has a millivolt (e.g. 30mV or 100mV) or non-amplified output it is a pressure transducer. If the pressure sensor has a voltage (e.g. 0-5Vdc, 0-10Vdc or 1-5Vdc) output it is an amplified voltage output pressure transducer. If a pressure sensor has a current loop output (e.g. 2 wire 4-20mA or 3 wire 0/4-20mA) it is a pressure transmitter. Simply we can tell as Transducer: Any physical Quantity is converted into Electrical Signal. Transmitter: to make the amplified RF electrical signal to radiation with help of Electric and maganetic signal.
Why are motors lamps and other resistors considered a loads in electrical circuits?
Because they use electrical energy to produce mechanical energy or heat energy
Speaker is electronic transducer?
Technically, a transducer is defined as a device, which converts other sources of energy such as heat, mechanical, pressure etc. into electrical energy, i.e., the output of a transducer is always electrical energy. Since, a speaker converts electrical energy into sound energy, it is not a transducer.
When energy changes from one from another?
When energy changes from one form to another it is through a process called transduction. This is done by a transducer, which is anything that converts energy. The human body converts chemical energy to heat and physical energy, nuclear reactors change heat energy to electrical energy, etc...
What is a device that transforms one form of energy to another?
Water heater converts electrical energy into heat energy Fan converts the same into mechanical Speaker converts electrical energy into sound using a magnetic field. A charger changes electrical energy into chemical energy A bulb filament changes electrical energy into light energy
What are the conversions of electrical energy give 5 examples?
-- An LED converts electrical energy to light energy. -- A coffee percolator converts electrical energy to heat energy. -- An old-fashioned light bulb converts electrical energy to light energy and heat energy, both at the same time. -- A loudspeaker or ear-bud converts electrical energy to sound energy. -- An electric motor converts electrical energy to kinetic energy. -- A radio transmitter converts electrical energy to low-frequency electromagnetic energy. -- A battery sitting in its charger converts electrical energy to chemical energy.
What energy does a toaster use?
It converts electrical energy into heat energy.
What is the name for an electrical load that converts electrical energy into heat energy?
A Resistor or Resistance
Can electrical energy be converted to other forms?
Yes.-- A toaster converts electrical energy to heat.-- A battery on its charger converts electrical energy to chemical energy.-- A fan or any electric motor converts electrical energy to mechanical energy.-- A light bulb converts electrical energy to electromagnetic energy in two main portions of the spectrum ...heat and light.-- Ear buds, bull horns, and loudspeakers convert electrical energy to sound energy.
A buzzer converts electric energy into what?
Mechanical and sound energy.
What kind of energy that flat iron converts electrical energy?
heat energy
Does light bulb converts kinetic energy into electrical energy?
No, it converts electricic energy into electromagnetic energy (heat and light)
What does bulb do in a circuit?
It converts electrical energy into heat and light.
Is there any device which converts heat energy to electrical energy?
All Generators, you use in day today life, witch run on Petrol,Kerosene and LPG are the devises witch converts heat energy to electrical energy.
