उदाहरण वाक्य
- Sometimes a rheostat is made from resistance wire wound on a heat-resisting cylinder, with the slider made from a number of metal fingers that grip lightly onto a small portion of the turns of resistance wire.

- A useful and practical lab standard resistance could be made with a certain length of resistance wire, such that it has a desired resistance with a stated precision at a stated temperature, and correction factors could be applied for other temperatures.
- Where the rheostat must be rated for higher power ( more than about 1 watt ), it may be built with a resistance wire wound around a semicircular insulator, with the wiper sliding from one turn of the wire to the next.
- If the potentiometer is attached to a constant voltage DC supply such as a lead acid battery, then a second variable resistor ( not shown ) can be used to calibrate the potentiometer by varying the current through the R 1 resistance wire.
- With food and ammunition for seven to 10 days, the Warsaw resistance wires Churchill, " The soldiers and the population of the capital look hopelessly to the skies, expecting help from the Allies . . . . Have you discussed in Moscow help for
- The active medium of the heater depicted at the right is a coil of nichrome resistance wire inside a fused silica tube, open to the atmosphere at the ends, although models exist where the fused silica is sealed at the ends and the resistance alloy is not nichrome.
- Because the resistance wire can be made very uniform in cross-section and resistivity, and the position of the wiper can be measured easily, this method can be used to measure unknown DC voltages greater than or less than a calibration voltage produced by a standard cell without drawing any current from the standard cell.
- No technology located in a circuit breaker or fuse panel could detect a high-resistance wiring fault as no measurable characteristic exists that differentiates a glow fault from normal branch circuit operation . "'Power Fault Circuit Interrupters "'( "'PFCI "') located in receptacles are designed to prevent fires caused by glowing connections in wiring or panels.
- My conjecture is that these two measurements will uniquely identify the odd resistor and its value ( ignoring the issues about measurement errors and resistor tolerances that Gr8xoz raises below I'm assuming that since we are allowed to use zero-resistance wires we also have a perfect ohmmeter and perfect one-ohm resistors ) . talk ) 00 : 22, 14 February 2011 ( UTC)
