Name two ways to increase the current to a load?
1) Use an operational amplifier.2) If voltage is not an issue, a transformer may be used.
How do you identify mosfet terminals?
mosfets come in 2 shape 1.round shaped(like bjt):hold it such that the pins face upwards and the knoch perpendicular to your eyes,then name pins as G,D,S in anticlock wise direction. 2.almost squre shaped.hold it perpendicular to your face ,then name them G,D,S from left to right
What compose a transformer substation?
A transformer substation comprises of transformation equipment- the transformers, the accessories for the connection of the transformers to the HT Lines (Primary Input)- usually concrete poles/steel towers, insulators etc; normally two or more transformers are present to allow maintenance and faults without the supply being interrupted. 2. The substation protective equipment such as lightning Arresters, Line Fuses and Breakers, Isolators (as appropriate) 3. Effective Earthing system and equipment 4. The Distribution equipment such as feeder pillar units, busbars etc depending on the type of transformer substation.

What are 2 examples of insulation?
Insulators of electricity: A person wearing rubbeInsulators of electricity: A person wearing rubber boots stepping on an exposed wire without getting electrocuted. Insulators of heat: A styrofoam cup containing hot water. It does not heat up or burn your hand a lot. In fact, it is so minimal that you hardly notice it.
Are non metal more electropositive than a metal?
There are two types of conductors 1- Metals and 2- Electrolytes, the compounds which become ionized in aqueous solution or in molten state are electrolyte so metal is a conductor of electricity but not an electrolyte.
Which is not an insulator?
As the "materials listed below" are not given, insulators are poor conductors of heat or electricity. On a periodic table, insulators tend to be towards the top right corner, so metals tend to not be examples of good insulators that comprise most of the periodic table with the exception of the nonmetals (top right corner, hydrogen). The metallic elements tend to end in -ium, such as aluminium, sodium, gallium, and francium. Others are gold, silver, copper, zinc, and nickel.
What material does not allow electrons to flow through it?
An insulator or a dielectric is the generic name for a material which does not allow electrons to flow through it. Many polymers such as PE, PP, PVC etc are insulators. Ceramics such as hardened clay are also insulators. Others include:glassrubberbakeliteoilsphosphorussulfurwoolsilicone rubberssilicone oilsteflonnylonpolycarbonateacrylicabsetc.Such materials are insulators. Insulators are materials that don't have free electrons available for the flow of electrons, which is called an electric current.Insulators are either pure elements which have a "full" outer electron shell (containing 8 electrons, which makes a full set for the shell) or they are compounds that have their electrons completely bound, with none available to flow away in a current.Further notes:All insulators can have their outer shell electrons broken loose if a high enough voltage is applied. This is called the dielectric breakdown voltage."Conductors" are elements that have only 1 or 2 electrons in the outer shell. These elements' electrons are loosely bound to their atoms and are already moving around in the crystalline structure. The application of a voltage to a conductor will cause these electrons to flow from negative to positive. This flow is what is called the current.
