Rheostat is an electrical instrument used to control a current by varying the resistance.
resistance definition. In electricity, a measurement of the difficulty encountered by a power source in forcing electric current through an electrical circuit, and hence the amount of power dissipated in the circuit. Resistance is measured in ohms.
hope it helps ;)

Rheostat
is a variable resistor, which is used to control the flow of electric current by manually increasing or decreasing the resistance. The English scientist Sir Charles Wheatstone coined the word rheostat, it is derived from the Greek word “rheos” and “-statis” which means a stream controlling device or a current controlling device.
Resistance
Resistance is the ability of the conductor to resist the flow of electric current through it.It depends on the nature of the conductor, its length,area of cross section of the conductor and its temperature.
resistance
is a measure of the opposition to current flow in an electrical circuit.
