WebAnswer (1 of 4): A rheostat is a variable resistance device whose value can be set smoothly by hand from 0 to 100%. Once set, it remains in that value within specified tolerance limits due to spring loaded contacts. So if you buy a 100 ohm rheostat then you can virtually get any value from 0 to 1...
WebThe function of a rheostat in an electric circuit is to increase and decrease the electric current. The rheostat only reduces the electric current to a certain level and does not block it completely. An infinite resistance is required to completely block the flow of electric … WebView Unit1_1_Basic circuit variables.pdf from ECE 3300 at Memorial University of Newfoundland.
