Can moment of inertia be negative?
No, moment of inertia cannot be negative as it is a physical quantity that represents an object's resistance to changes in its rotation. Negative values for moment of inertia do not have physical meaning.
Is it possible for the moment of inertia to have a negative value?
No, the moment of inertia cannot have a negative value. It is always a non-negative quantity that represents an object's resistance to changes in its rotational motion.
What does the slope of resistance Vs temperature curve gives?
The slope of a resistance vs. temperature curve gives the temperature coefficient of resistance, which quantifies how much the resistance of a material changes with temperature. Positive values indicate the resistance increases with temperature (e.g., in most metals), while negative values indicate the resistance decreases with temperature (e.g., in semiconductors).
What is the temperature co-efficient of a resistance of a thermister?
The temperature coefficient of a thermistor is a measure of how much its resistance changes with temperature. It is typically expressed in units of percent resistance change per degree Celsius. Negative temperature coefficients mean the resistance decreases as temperature increases, while positive coefficients mean the resistance increases with temperature.
What does it mean to be counter-friction?
Being counter-friction means to act in opposition or resistance to friction. It involves implementing measures or strategies to counteract the negative effects of friction, such as reducing resistance or increasing efficiency.
Why it is said to be negative resistance region?
A negative resistance region is where the current goes up while the voltage goes down, or vice versa. This is a characteristic of the esaki or tunnel diode, when it is in its tunnel region.
Why there is gap in tunnel diode voltage in experiment?
negative resistance region
Why does a SCR have negative resistance?
Whenever you measure resistance, the resistance itself cannot be negative!When an SCR (Semiconductor Controlled Rectifier) is not conducting, it has a high resistance between its anode and its cathode. When its gate is triggered and the SCR is conducting, it has a low resistance between its anode and its cathode.For more information about SCRs, see the answer to the Related Question (for which a link is shown below) and also the Related Link.
How the negative resistance region of tunnel diode useful in microwave application?
amplification
Why tunnel diode are used in negative resistance region?
because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
What type of diode exhibits negative resistance?
A Tunneldiode, usually made of GaAS. In a part of its curve it has a negative resistance. This means that when you increase the voltage in that region, the current will drop.
Define and explain Negative resistance?
Plot a V-I curve for an ordinary resistor and you'll get a straight line with positive slope: as current goes up, so does voltage drop across the component. The V-I curve for some semiconductors features a region of negative slope. When the device is operating in this region, it exhibits negative resistance, which can be extremely useful when designing stable feedback systems.
Which diode used for signal amplification zener or schottky or tunnel or none?
The diode that has a negative resistance region in its voltage-current curve.
In the inverted region of Marcus, what unique characteristics or phenomena can be observed?
In the inverted region of Marcus, unique characteristics or phenomena such as negative differential resistance and negative differential capacitance can be observed. These phenomena involve the decrease in current or capacitance with increasing voltage, which is opposite to the typical behavior in electronic devices.
Why does the resistance of a thermistor decrease as the temperature rises?
Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.
How ujt exhibits negative resistance characteristics?

What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
