What is the effect of temperature on ohms law?
AnswerOne of the conditions for Ohm's Law to apply is that the temperature of a conductor MUST remain constant. And, unfortunately, this is difficult to achieve because as the applied voltage increases, the resulting current causes the temperature of the conductor to rise -thus negating Ohm's Law!!For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage. If it doesn't, then the conductor/device is NOT obeying Ohm's Law. Period! So if, for example, you increase the voltage across a lamp, you will find that the ratio varies as the voltage increases, and this is because the resistance is increasing due to an increase in temperature. So, in this example, the temperature is the reason why lamps don't obey Ohm's Law.

How can thermocouple measure the temperature?
Thermocouples are two junctions of two dissimilar metal conductors. One junction is the sensing junction and the other is the reference junction. The voltage between the two junctions depends on the temperature difference between the junctions (Seebeck effect). The voltage can be measured and the temperature difference determined based on known readings of the voltage produced by the metals. If the temperature of the reference junction is known, then the temperature of the sensing junction can be calculated.
How does a Thermo-coupler work when it has 2-wires connected approx halfway up the copper what does the 2-wires do?
The two wires on a thermocouple create a junction where the two dissimilar metals meet. When there is a temperature difference at this junction, it generates a small voltage, known as the Seebeck effect. This voltage is used to measure the temperature of the system the thermocouple is monitoring.
How a thermocouple device works?
A thermocouple consists of two different metals joined at one end, known as the hot junction, and connected to a temperature measuring device at the other end, called the cold junction. When there is a temperature difference between the two junctions, a voltage is generated due to the Seebeck effect. This voltage is then measured by the temperature device and converted into a temperature reading.
What is the effect of temperature on PN junction diodes?
As temperature rises more minority carriers are created, causing leakage across the junction to rise. This can cause runaway and eventual destruction of the junction.

What would cause the barrier potential to decrease from 0.7 V to 0.6 V?
The barrier potential may depend on the exact material; but you can't normally change that. It may also depend on temperature.Also, such a barrier potential is not fixed at some value (like 0.7 V); however, it's often close enough that you can consider it to be constant. But actually, the barrier potential depends on the current. At higher currents, the potential is slightly higher.
What types of transistors are the following - BJT PCT UJT SBT FET GJT AJT DFT?
The BJT is the bipolar junction transistor, the PCT is the point contact transistor, the UJT is the uni-junction transistor, the SBT is the surface barrier transistor, the FET is the field effect transistor, the GJT is the grown-junction transistor, the AJT is the alloy-junction transistor, and the DFT is the drift field-junction transistor.
How do thermocouples work and what is their principle of operation?
Thermocouples work by measuring temperature through the voltage generated when two different metals are joined together. This is known as the Seebeck effect. When there is a temperature difference between the two junctions of the metals, it creates a voltage that is proportional to the temperature difference. This voltage can then be measured and used to determine the temperature.
What is voltage equivalent of temperature?
The voltage equivalent of temperature is often represented through the concept of thermoelectric effects, particularly in thermocouples, where a voltage is generated in response to a temperature difference. This relationship is described by the Seebeck effect, where the voltage produced is proportional to the temperature gradient. In thermodynamics, temperature can also be expressed in terms of energy per unit charge, linking it to the concept of voltage in certain contexts, such as in the behavior of semiconductor materials. Overall, while not directly equivalent, voltage can serve as an electrical representation of temperature in specific applications.
What is thermal induction and please explain Seebeck and Peltier effect?
Thermal induction refers to the generation of electric currents through temperature differences in a material. The Seebeck effect involves the creation of a voltage between two different materials when there is a temperature difference between them, while the Peltier effect is the absorption or release of heat when an electric current flows through a junction between two different materials. These effects are the basis of thermoelectric energy conversion.
