A rheostat is defined as A variable resistor which is used for controlling the flow of electric current either by increasing or decreasing the resistance. The term rheostat was coined by the English scientist Sir Charles Wheatstone and is derived from the Greek word “rheos” and “statis” which means current … See more There are three main parameters of any electrical circuit, and they are: 1. The voltage applied to the circuit 2. Current through the circuit 3. … See more The construction of rheostat and potentiometerare similar. There are three terminals in the rheostat with two connections. The construction of rheostat is shown below: The three terminals of the rheostat are denoted … See more WebIt's done so because to find resistance according to Ohm's law, we are dividing the voltage by current. So when we find the slope, which is. (Δy/Δx) of the straight-line graph (i.e., resistance), we need the voltage to be on the Y-axis (numerator of the fraction) and current on the X-axis (denominator). Hence, the other way round.
What is the function of rheostat in the circuit? - Toppr Ask
WebJan 5, 2010 · The function of rheostat is to provide variable resistance in a circuit. For example, if for some experiment the resistance in the circuit needs to be increased or decreased, then rheostat can be used. Regards, Team, TopperLearning.
