A resistor that indicates the plus and minus limits of ohmic value is typically marked with a tolerance percentage, such as ±5% or ±10%. This specification shows the allowable variation from the nominal resistance value. For example, a resistor labeled as 100 ohms with a ±5% tolerance can actually have a resistance value between 95 ohms and 105 ohms. This tolerance is crucial for ensuring that the resistor meets the required performance in a circuit.

What is the nature of V-i graph?
The V-I graph, or voltage-current graph, illustrates the relationship between voltage (V) and current (I) in an electrical circuit. For ohmic materials, the graph is a straight line, indicating a linear relationship where voltage is directly proportional to current, described by Ohm's Law (V = IR). Non-ohmic materials may exhibit non-linear characteristics, resulting in curves that reflect varying resistance with changing voltage or current. The slope of the line or curve on the graph indicates the resistance of the material.
What is the slope of the graph of versus for an ohmic material?
"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.
What is the difference between Low OHIMC Distribution and High OHMIC Distribution?
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.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
What happens to the resistance of a common ohmic resistor when it is heated?
When a common ohmic resistor is heated, its resistance typically increases.
Is a ceramic resistor ohmic?
yes
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 is an example of an ohmic resistor?
i give the ans why iam asking you
What is the difference between ohmic and non ohmic elements?
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.
Is resistor an ohmic device in ac circuit?
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
How can you check if 50 mega ohms resistor is open?
use a merger tester, if there are no indication to certain number of ohmic (50 M), that is mean resistor is open.
What is the difference between resistor and metrosil?
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.
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.
Why is a light bulb not an ohmic resistor?
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.
Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
