Usually RFID tags would get the power from the reader.
The type of RFID tag you are referring to is likely a passive device. It gets read by stimulating it with a certain RF frequency and then looks for a unique return. Hence the tag life is essentially forever.
Tri Fuel power generators can be operated using natural gas, gasoline or propane and it does not take too much effort to switch from one fuel source to another. There is not much mechanical work required in order to use the source or even to change the source from one type to another.
There is one type of parallel circuit. An example of this type of circuit is the electrical wiring in a house. These circuits are generally very complex and have a single power source.
A forward declaration is simply a declaration of an identifier that will be defined at a later point during compilation. It is quite common to separate declarations from their definitions using header files (.h) and source files (.cpp). The header essentially contains all the forward declarations of all the definitions contained in the source file. It is also common practice to use forward declarations when a header contains pointers to a type, rather than references. If it includes references, then you must include the header file for those references, but if they are pointers then you only need a forward declaration of the type (before it is used) and the actual header that contains the full declaration can be included in the source file instead.
smaw and tig(gtaw) are using CC source. because these both types using manual wire feeding. so welder can not able to maintain constant arc length. change in arc length will change voltage. so it needs power supply which should not affected by this arc length = voltage changes. that's why CC type is used for these process. in CC type source change in voltage will not change current much.

All types... depending on frequency and application. Lower frequency RFID's are typically near field and use inductive antenna designs, higher frequency ones use far-field designs. Low frequency RFID's like the TIRIS pet ID's use coils of wound wire. HF type RFID's like MiFARE use simple planar loop antenna designs. Most VHF RFID's use dipole and modified dipole designs with reflector elements. UHF and microwave RFID's frequently use patch and slot antenna designs.

Coal power plants are the largest source of power in Michigan.

Consider a battery for a moment. A battery can be a source or sink type of power source. A light bulb would be considered a source current. When a battery or other item is being charged is it considered a sinking source.
