An unknown DC voltage, in series with the galvanometer, is then connected to the sliding wiper, across a variable-length section R 3 of the resistance wire.
22.
The final step is to calculate the unknown voltage from the fraction of the length of the resistance wire that was connected to the unknown voltage.
23.
Some heat with a high resistance wire; that is, the wire gets red hot, protected by a cage to keep the hot wire away from the person.
24.
Other reasons for a no-start or barely start condition include, for openers, a marginal starter motor and high-resistance wiring in the primary ( starter motor ) circuit.
25.
Avoid using a resistance heat element like ones in a toaster, which have the line voltage present on the resistance wire, or anything with an energized conductors exposed.
26.
To control the temperature of the interior of robosquirrel s body, a coiled Nichrome 80 resistance wire was inserted and a cartridge heater was inserted into its tail.
27.
In operation, a current flows through the filament ( heater ) a high resistance wire made of nichrome and heats the cathode red hot ( 800 1000 �C ).
28.
Containing 8 meters of coiled alloy resistance wire, they emit a uniformed heat across the entire surface of the heater and the ceramic is 90 % absorbent of the radiation.
29.
The way to make a strong magnet is not only to have many turns, but also thick, low-resistance wire, and something to pump a heck of a lot of current through it.
30.
"' Resistance wire "'is wire intended for making electrical resistors ( which are used to control the amount of current in a temperature coefficient of resistivity and corrosion resistance play a large part in material selection.
