An electric soldering iron is heated by an electric resistance coil inside.
Others may be heated either by a gas(like propane) flame, or by sticking them in a forge between uses.
The type of material used to connect the pieces. Solder is used on copper or brass. Brazing uses a copper alloy and is used on Iron based items. Same process in how it is done.
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
An electric current goes through an electric circuit, if it is closed.
Its all electrical, but referring to electronics would be solid state devices such as tiny resistors ,tranistors soldering work found on devices such as Computer chips and Vehicle ECU's
the High voltage rated diodes are power diodes while of low rating or normal voltage rating are considered to as ordinary / normal diode
When soldering a person can use an electric tool or a torch. The torch uses a flame, while an electrical tool has a soldering tip which is heated.
really no difference except for the quantity of soldering.
same concept, silver soldering requires higher temperatures usually
EXTRA!!
The major difference between a solution and an ordinary mixture is that solution is homogeneous and an ordinary mixture is heterogeneous.
The difference between a tied grant and an ordinary grant is that a tied grant has conditions and the ordinary grants don't!
difference between ordinary prism and constant deviation prism
Flux helps promote soldering. Soldering paste might contain flux and other items to help promote soldering. The paste helps hold the flux in place while beginning to solder.
What is the difference between an ordinary transformer and resonant coupling energy transfer?
