"Ohmic" means it obeys Ohm's law (V=IR, i.e., voltage = current x resistance). Since Ohm's law can be understood to be a definition of resistance, what this really means is that the material has a constant resistance. In such a case, the slope of current as a function of voltage will be a straight line passing through the origin.
Low OHIMC (Open High Impedance Microphone Circuit) distribution typically refers to a scenario where the circuit has a higher input impedance, resulting in less loading on the microphone and improved sensitivity, making it suitable for capturing quiet sounds. In contrast, high OHIMC distribution involves lower impedance, which can lead to greater noise and distortion but may be necessary for specific applications where robust signal strength is crucial. The choice between the two depends on the desired audio quality and application requirements.
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
When a common ohmic resistor is heated, its resistance typically increases.
yes
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.
i give the ans why iam asking you
An 'ohmic' resistor is one which obeys Ohm's Law. For Ohm's Law to apply, the resistance of a circuit must be constant over the range of incremental voltages applied to it. If the resistance changes over an incremental range of voltages, then it is said to be 'non-ohmic', and it does not obey Ohm's Law.
Well, yes, sort of. "Ohm" is a measurement of resistance, so I would say yes. Although I'm not sure of 'ohmic' is really a word
use a merger tester, if there are no indication to certain number of ohmic (50 M), that is mean resistor is open.
A resistor is a passive two-terminal electrical component used to introduce resistance in an electric circuit. Metrosil is a type of resistor that is specifically designed to protect electrical equipment from overvoltage and lightning strikes by rapidly switching to a high resistance state when a voltage surge is detected. Essentially, Metrosil is a specialized type of resistor with specific protective properties.
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.....thermistors are not ohmic.
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.
