What are two things that can change the amount of current that flows?
voltage and resistance There is also temperature.
Is the resistance of a resistor the same as voltage changes?
Yes and no. As voltage changes, current changes, causing power to change, with the end result that temperature changes. Most resistors have a small temperature coefficient, so their resistance will change slightly as the voltage changes.
If thermocouple shows a voltage corresponding to the differential temperature bw junctions then why is there still a voltage when you keep both the junctions at the ambient temperature?
A: THERMOCOUPLE has the characteristic of both negative and positive temperature a room temperature it is still sensing the temperature it will not go to zero except for a specific temperature and that will change for each metal used
What is temperature cofficient in pn junction?
Temperature coefficient of the PN intersection voltage to balance the temperature coefficient of the warm voltage.
What is the relationship between temperature and voltage amplification Theory and Mathematical Information?
With higher temperature, low voltage
How does the ac resistance of a diode change as the voltage increases?
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
What is sencer?
If you mean sensor, a sensor is a device that changes based on some phenomenon and this change is used to measure the change in the phenomenon.For example, assume a device produces a voltage and the amount of that voltage depends on the temperature of the device. It can be used as a sensor for temperature. Assume you put the device in water and another device measures the voltage produced by the sensor. Based on the voltage of the sensor it can display the temperature of the water. So, in this example, the sensor senses the temperature of the water.

How does changing the temperature of solutions affect the amount of voltage that is going to be produced in votaic cell?
Changing the temperature increases the change in energy.

What is the relationship between current and voltage in a thermistor?
V=IRR changes as a result of the change in temperature.

How does a thermocouple work on a gas boiler?
A Thermocouple is simply a temperature-sensor consisting of a junction between two metals, where the tiny voltage between them varies with temperature. This change in voltage can be detected and acted upon by the electronics controlling such things as boilers.
Electronic temperature sensor?
Electronic temperature sensors are basically a transducer which convert the heat energy to equivalent voltage . they are thermocouple and also some heat sensing device are available which change their electronic parameter when temperature change those are used in vehicle and aircraft for temperature controlling and cooling.
What is supply and temperature independent biasing?
The signal or output of a circuit is often affected by changes in the supply voltage and/or ambient temperature. A biasing circuit is designed to consistently output a selected voltage (or current). Depending on the circuit topology, a change in supply voltage or temperature can cause the intended value to drift. In an increase in temperature can, for example, increase resistances in a circuit. Such effects are usually undesireable and thus a supply/temperature independent bias would be needed. Electronic component manufactures will frequently provide tolerances for outputs relative to changes in supply voltage and temperature.
