Rheostat, adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit.The rheostat can adjust generator characteristics, dim lights, and start or control the speed of motors.Its resistance element can be a metal wire or ribbon, carbon, or a conducting liquid, depending on the application. >> They were developed almost 150 years ago for bicyclists. << Measure the new balancing length l 2 for the cell E 2 based on this point. Resistance Box Definition: The box which contains the resistors of different values for estimating and comparing the resistance is known as the resistance box.The accuracy of the resistance box is very high. endstream As such it will be used in experiments to adjust resistance within a circuit to fine tune or derive precise values. stream /Subtype /Form The positive terminal of the cell of e.m.f. << It should touch the wire gently.
