For a material to be 'ohmic' or 'linear', it must obey Ohm's Law. For Ohm's Law to apply, the ratio of voltage to resistance must be constant for variations in voltage.
An incandescent lamp's filament is manufactured from tungsten, which is 'non-ohmic' or 'non-linear' because the ratio of voltage to current changes for variations in voltage. In fact, MOST conductors and electrical devices (such as diodes) are non-ohmic.
If you were to conduct an experiment that allowed you to record the variation if current flowing through a tungsten filament for variations in voltage, the result would be a curved graph line -in other words, a 'non-linear' (therefore, 'non-ohmic'), graph line.
So, to directly answer your question, NO, a tungsten filament is not an ohmic material.
Wood can not let a light bulb light up because wood is a very poor conductor of electicity. A better conductor would be types of metals such as copper or gold, which is used in many electronics.
what is a C. O. light bulb?
Yes, a light bulb is matter.
The light bulb its self is non renewable, it is replaceable. The electricity that powers the light bulb can be renewable.
It is the Incandescent light bulb. Most of the energy are lost as heat
A light bulb is not an ohmic resistor because its resistance changes with temperature. As the filament heats up when current passes through it, its resistance increases, violating Ohm's law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points. In contrast, ohmic resistors maintain a constant resistance regardless of temperature or current. Thus, the relationship between voltage and current in a light bulb is nonlinear.
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
ohmic conductors are those which obey ohm's law
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.
No, a light bulb is not a conductor. A light bulb is made of materials that act as insulators, such as glass and tungsten. The filament inside the light bulb serves as a resistor to generate light when electricity passes through it.
You can test if something is an insulator or conductor by connecting a circuit with a power source and a light bulb. If the material allows the light bulb to turn on, it is a conductor. If the light bulb does not turn on, it is an insulator.
Diode is a non-ohmic conductor since in diodes current-voltage relation ship does't obey Ohm's law....the relationship between current and voltage is nonlinear here,...
If a light bulb is touched by a conductor to complete the circuit, it will turn on if the circuit is closed and working properly. The conductor helps to create a path for the electricity to flow from the power source to the light bulb, allowing it to illuminate.
yes
A lemon can power a light bulb because of the acid in it. The acid is used as a conductor and powers the lemon.
It has high resistance.
