What is the purpose of an cathode and an anode in a diode?
The cathode and anode are simply two terminals of a semi-conductor junction. In a normal diode, forward bias occurs when the anode is more positive than the cathode.
Why are ohmic materials useful?
because ohmic materials such as resistors can be placed in ur bedroom for safe sex
What are the examples of semiconductor devices?
lED, or light emitting diode, chips an others
Are fixed resistors ohmic?
yes
What are non ohmic devices give an example?
non ohmic devices are diodes, LED's, Thermistors, LDR(light dependent resistors, cells in series.
What are ohmic and non - ohmic conductors?
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
What is an ohmic conductor?
ohmic conductors are those which obey ohm's law
Is the 10 ohm resistor ohmic or non-ohmic?
If it has constant temperature (one can do this by dipping it in a beaker of water) it can be considered an ohmic conductor since Ohm's law states that the Voltage and amperage are directly proportional in a metallic conductor of constant temperature.
What are Ohmic and Non - Ohmic conductor?
ohmic ocnductor is a material which obeys ohm's law: i.e. the voltage and current are directly proportional 2 each other anda non-ohmic ocnductor is a material which doesn't obey ohm's law:)
What is non ohmic material?
A 'non-ohmic' conductor is one that does not obey Ohm's Law -i.e. the ratio of voltage to current is not constant when the voltage across it varies.
Define nonohmic materials and give examples to them?
define the nonohmic metarials and give examples to them
Is metal wire an ohmic conducter?
That depends on the what substance the wire is made from. Wires made from metals, such as iron, copper, gold, are good conductors. Wires made from aluminum would not be as good of a conductor.
What is the definition of an ohmic conductor?
An ohmic resistor is a resistor that obeys Ohm's law, and a non-ohmic one dose not. All resistors resistance will begin to change as there temperature changes, and often we need a resistor with a steady resistance, thus some resistors, which we refer to as ohmic, will disperse the heat being generated and therefore it will keep a steady resistance. Resistors that do not disperse their heat will have varying resistances and therefore are non ohmic. Ohms law, named after the German physicist Georg Ohm, states that the current through a conductor, between two points, is directly proportional to the potential difference (voltage) across the two points, and inversely proportional to the resistance between them. ~Ben Frilay-Cox
If you decrease resistance the current will increase or decrease?
It depends on whether the material is ohmic or non-ohmic.If it is ohmic, then it will obey Ohm's Law, and its resistance will remain constant if the current decreases.If, on the other hand, it is non-ohmic, it will not obey Ohm's Law and, if the temperature of the conductor falls (assuming it is a metallic conductor) due to the fall in current, then its resistance will fall too.
Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
In4001 diode what is IN in it?
It means that the semi conductor have only one pn junction
Define nonohmic materials?
Tungsten
