rheostats are adjustable power resistors. perfect for low voltage applications (i.e. 5v, 12v, 24v). the low cost option for loading. another benefit is that they can be adjusted under load.
instead of building a test rig with innumerable wires, and risking equipment damage or fire hazard, ed&d has designed and developed a cutting-edge line of resistive load banks.
