Does a thermocouple produce constant current or will it just give a single electric pulse when a const temp diff is maintained betw its terminals?

The thermocouple is normally regarded as a high-impedance voltage source. As such,
the voltage across it due to temperature is sensed, and processed by an amplifier stage
that doesn't rely on it to supply appreciable current. You should think of it as a constant
voltage source with a high internal resistance.

Which thing always remains constant inside a conducting sphere?
An electric charge cannot be established or maintained inside a conductive container. This is the basis of the Faraday Cage, used to isolate a working space from electric fields.
What device is used to transform thermal energy to electric energy?
A thermocouple does this, but a turbine does also.
Is an electric field associated with an electromagnetic wave constant in time?
No, the electric field oscillates in magnitude and direction as it propagates in the electromagnetic wave.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
If potential is constant throughout a given region of space can you say that electric field is zero in that region?
If the electric field is zero, the electric potential is a constant value, but it does not tell you what that value is. All the electric field tells you is how the electric potential changes within the region you are looking at. If the electric potential at one end of a cylindrical region is 7 V and the electric field is zero within the whole cylinder, then the electric potential is 7 V at the other end, or somewhere in the middle, or on the side, and so forth. An electric field of zero tells you the potential does not change, but doesn't say anything about what it is outside of the region you're looking at.
who was first made electric power using fire and thermocouple?
Denis Papie was the man who first made electric power using fire and thermocouple.
Why would you use a thermocouple for controlling an electric frying pan?
Since a thermocouple responds to temperature, it can be used as a thermostat, to set a specific temperature for your electric frying pan.
Does an electric heater do the opposite of a thermocouple?
In effect it does. Electricity applied to the heater produces heat. Heat applied to the thermocouple produces electricity.
Why do electric cells have 2 terminals?
to form an electric circuit two terminals are required it is being closed and electric current passes through it .
What is the energy conversion for a thermocouple?
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.
Why do electric cell have two terminals?
They are the negative and positive terminals. Higher potential andl ower potential terminals

What device is used to transform thermal energy to electric energy?
A thermocouple does this, but a turbine does also.
How many terminals are there in a bulb?
There are two terminals on an electric bulb whether AC or DC.
Introduction of heating effect of electric current and electric heater fuse metals used for thermocouple?
Can heat energy be converted to light energy and how?
What is Thermocouple?
In terms of security, the thermocouple is an integral component of the furnace. A little flame that burns continuously is a thermocouple. It is frequently employed in gas furnaces that have standing pilots. In order to maintain a warm tip, the thermocouple's top is placed in the flame. When the pilot flame goes out, the thermocouple automatically shuts off the gas valve in the furnace. Thermocouples are used in everyday good ,electric power generator etc you can avail thermocouple for best price at partshnc website
When wires are connected to the terminals of the battery what causes electric current in the circuit?
The voltage (V) between its terminals. ~Gabby
