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 resistor indicates plus and minus limits of ohmic value?
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 does i-v graph of conductor represent?
The I-V graph of a conductor represents the relationship between the current (I) flowing through the conductor and the voltage (V) across it. In an ideal conductor, this relationship is linear, indicating that the current is directly proportional to the voltage, as described by Ohm's Law (V = IR). The slope of the graph corresponds to the conductor's resistance. Deviations from linearity can indicate non-ohmic behavior, where the resistance changes with voltage or current.
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 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.
Differentiate between ohmic and non ohmic substances?
which law follow non ohmic substances
Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
Is diode ohmic or non-ohmic conductor?
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,...
What are ohmic and non - ohmic conductors?
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
Why the resistant in ohmic devices is constant and in non ohmic not constant?
the resistant in ohmic devices is constant because it depend on temperature ..and temperature is constant independent of polarity of potential difference...btin non ohmic the tempt increase with voltage which increase due to the heat increase beacue of power dispition....collision of electrons increases find more resistenc for passing so resistence increases
What is Low OHMIC?
Low ohmic refers to materials or components that have a low electrical resistance, typically measured in ohms. Such materials allow electric current to flow more easily, leading to increased conductivity. Low ohmic components are often used in applications where minimal energy loss and efficient current flow are essential, such as in power distribution systems and electronic circuits.
Example of non -ohmic and ohmic materials?
iron,gold
What is an ohmic conductor?
ohmic conductors are those which obey ohm's law
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.
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.
