contact resistance उदाहरण वाक्य
उदाहरण वाक्य
- The dependence of contact resistance on the details of the interfacial chemistry is what makes the reproducible fabrication of ohmic contacts such a manufacturing challenge.
- The contact resistance is not stable immediately after contact closure, and drifts, mostly downwards, for several seconds after closure, the change perhaps being 0.5 ohm.
- The difference between resistance derived from two-lead and four-lead methods is a reasonably accurate measurement of contact resistance assuming that the leads resistance is much smaller.
- This is low enough that it may be used with safe low voltages, yet high enough that the currents remain low, avoiding problems with contact resistance.
- With this type of meter, any voltage drop due to the resistance of the first pair of leads and their contact resistances is ignored by the meter.
- The approximations used here ( linear potential drop across the channel region, constant contact resistance, . . . ) lead sometimes to the channel dependent contact resistance.
- For this, vias comprising tightly packed ( > 10 13 cm " 2 ) metallic CNTs with low defect density and low contact resistance are needed.
- The approximations used here ( linear potential drop across the channel region, constant contact resistance, . . . ) lead sometimes to the channel dependent contact resistance.
- However, ohmic contact resistance heating is generated when peak current flows through these individual microscopic contacting points, which are critical areas for the overall internal resistance of the capacitor.
- This may be due to dirt or corrosion and is typically perceived as " crackling " as the contact resistance fluctuates; this is especially noticed as the device is adjusted.
