Root Explanation

Rheostatic → It is formed from "rheo-" (from Greek "rheos", meaning flow) and "static" (from Greek "statikos", meaning causing to stand or stationary). The word "rheostatic" refers to devices that control the flow of electric current by varying resistance, thus affecting the flow of electricity.

Memory Tip

Think of 'flow' ('rheo-') being controlled to make something 'stand still' or stationary ('static'). This helps you remember that 'rheostatic' relates to controlling the flow of electricity.
