What are the classifications of diodes?
a diode is a device that alows current to flow in one direction you have power diodes which are used in rectification processes and high current operations but the two main families of diodes are solid state diodes or valve operated diodes.
What state of matter is the element strontium in?
It is in a solid state of matter.
What does OA stand for in OA 79 germanium diode?
It is not "OA 79" it is "0A79", that is the digit zero not the letter "O".The designation of 0A79 is inherited from old designation system for Vacuum Tubes.0 - 0V heater/filament or no heater/filament meaning a Cold Cathode deviceA - Low Current Diode79 - an arbitrary unique number identifying the specific device type, in this case a solid state germanium diode not a vacuum diode or gas diode
Why tungsten filament does not obey ohm's law?
A tungsten filament does follow Ohm's Law at any instant of time. You may be confused in that the filament resistance changes from its "cold" state to its "hot" state. When cold the resistance is about 1/15 the resistance of what it is when the filament heats up, which happens very quickly. At any instant Ohm's Law holds. When the voltage is applied you have an initial current draw that exceeds the steady state current draw based on the change in resistance.AnswerOhm's Law either applies, or it does not. It cannot apply 'at an instant of time' -a change in current is either proportional to a change in voltage, or it isn't!A tungsten filament does not obey Ohm's Law, because the current flowing through the filament does not increase in proportion to the applied voltage. This is because the resistance changes due to the filament's increasing temperature as the applied voltage increases. This is why Ohm's Law specifies that current is proportional to voltage, provided the temperature remains constant.Although tungsten doesn't obey Ohm's Law, the so-called Ohm's Law equation applies whether a circuit obeys Ohm's Law or not. This is because the formula is really derived from the definition of the ohm, and not from Ohm's Law itself, which makes absolutely NO reference to resistance!
Where does ice come from?
Ice comes from when water is freezed from its liquid state into its solid state, ice.
