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 carbon resistance is a non ohmic conductor?
Yes, carbon resistance is considered a non-ohmic conductor. Unlike ohmic materials, which follow Ohm's Law (V = IR) with a constant resistance, carbon's resistance can change with temperature and the applied voltage. This means that its current-voltage relationship is nonlinear, characteristic of non-ohmic behavior.
What is a nonohmic resistance?
A nonohmic resistance is a type of electrical component that does not follow Ohm's law, meaning that its current-voltage relationship is not linear. In nonohmic materials, the resistance can change with voltage, current, or temperature, resulting in varying resistance under different conditions. Examples include diodes, transistors, and certain types of thermistors. This behavior contrasts with ohmic resistors, which maintain a constant resistance regardless of the applied voltage or current.
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:)
Is copper an ohmic conductor?
Yes of course all transition metals are ohmic conductors. (voltage proportional to current at constant temperature with resistance rising or gradient of V-I graph decreasing at higher temperatures) Believe me I've just done physics A.S.
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.
Is LDR an ohmic conductor?
A Light Dependent Resistor (LDR) is not considered an ohmic conductor. Ohmic conductors follow Ohm's Law, where the current through the material is directly proportional to the voltage across it, resulting in a constant resistance. In contrast, the resistance of an LDR changes with varying light intensity, leading to a non-linear relationship between voltage and current. Thus, its behavior does not conform to ohmic characteristics.
What is current for an ohmic conductor?
Current in an ohmic conductor is the flow of electric charge that is directly proportional to the voltage applied across it, as described by Ohm's Law (V = IR), where V is voltage, I is current, and R is resistance. In an ideal ohmic conductor, this relationship holds true regardless of the magnitude of the voltage, indicating that the resistance remains constant. Therefore, as the voltage increases, the current increases linearly, reflecting the conductor's ability to maintain a consistent ratio of voltage to current.
Why is a filiament lamp a non ohmic conductor?
A filament lamp is a non-ohmic conductor because its resistance changes with applied voltage. As the voltage increases, the resistance also increases. This is due to the temperature-dependent behavior of the filament material, which causes the resistance to vary.
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.
