Check for any relay and or blown fuses
Mercury is used in switches because it is a liquid metal, conducts electricity, and is very stable. Switches made from mercury are also called "Silent Switches", since the switching occurs when the mercury makes the connection between the contacts, instead of a mechanical switch. The mercury is usually contained in a small glass vial within the switch. It is also commonly found in home thermostats, used to control heating and/or air conditioning systems.
Air conditioning has affected American society in a positive way. Because of its ability to cool off rooms during the hot summer days, air conditioning provides comfort to those who would have to find another way to fight high temperatures.
because that's what air conditioning does. it cools the air.
because it is
Probably because it was the first kind of conditioning to be demonstrated and studied. See Pavlov As eluded to above, classical conditioning is called such because it was the first kind of conditioning to be studied and demonstrated. However, the term "classical" also is used to differentiate this type of conditioning from "Operant Conditioning" which was first demonstrated by B.F. Skinner.
Mixtures and Solutions are the same because they both use each other to do what they do. Solutions use Mixtures because you have to mix things together that are solutions to get solutions. Although mixtures don't need solutions to do anything solutions are very helpful.
no because there is no switches
Switches are made of plastic or bakelite because they don't conduct electricity.
Yes, because the light is using 3-way switches. There is always "power" travelling between the switches.
npn and pnp transistors have the same operation as one another, they are both switches, pnps may be known as inverted switches because they work on negative voltage supplys and not positive voltage supplies.
Because in the switch there is
No, because other solutions are not liquid
