The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. See resistivity. The resistance of a conductor, or circuit element, generally increases with increasing temperature. When ...
The effect of temperature on the resistance of the conductor isdirectly proportional to each other. The increase in temperature of the conductor increases its resistance and makes it difficult to flow current through it. As discussed above, the movement of free electrons creates the flow of current...
Rather than use a cell directly, as in the figure, it is better in practice if we use a Zener diode or bandgap reference to provide a stabilized p.d. (p. 108). If the value of V is fixed in this way, the equation shows that R is proportional to 1/I. We can calibrate the sca...
The average of the square of this voltage is directly proportional to the Kelvin temperature. Properly calibrated, a measurement of the voltage yields the Kelvin temperature. Although the technique requires sophisticated electronic instrumentation, it is one of the few alternatives to gas thermometry ...
What is electrical susceptibility? Name the factors on which the heat produced in a wire depends when current is passed in it. What is thermo emf? What is meant by thermal conductivity? To how many decimal places, can you measure resistance using the P.O. box?
Stellite 6, NiCrBSi, Hastelloy C-276, Cr_3C_2-NiCr, Cr_3C_2-CoNiCrAlY and TiMoCN-Ni powders were used to prepare several set of samples. The obtained results show that the abrasion resistance is not directly proportional to the hardness. The difference in microstructure between cermet and ...
It indicates that the EID variation changes the shape, size, and current path of the slag pool, and, as a result, the current density, heat generation, and melting power are directly proportional to the EID, while the electrical resistance of the slag pool is inversely proportional to the ...
Although oxide-based resistive switching memory (OxRAM) is one of the strong next-generation high capacity memory candidates, it has the critical disadvantage that deviations of resistance levels is too severe to be adopted as a high capacity memory device. More specifically, it is known that the...
in a well within a copper block whose temperature is to be measured. The four short capsule lead-wires, which pass through a platinum-glass seal, are connected to longer insulated copper leads that are thermally anchored to prevent heat transfer to the capsule. The glass seal and the gas pr...
[22]. TheOhmic resistanceand polarization resistance mainly contribute to the total internal resistance. In standard operating conditions, Ohmic resistance is majorly responsible for the potential drop, which is directly proportional to the current value as perOhm's law. Again, resistance deterioration ...
