The invention discloses a stepless regulation load resistor device and regulation method for an electrical test, the device comprises a load resistor unit and a control protection unit, the load resistor unit comprises a plurality of resistor loops which are connected in parallel, and each resistor loop comprises a switch module and a resistor module which are connected in series; wherein the resistor modules in part of the resistor loops are dry resistors, and the resistor modules in the other resistor loops are water resistors; and the control protection unit is connected with the switch module of each resistor loop and is used for controlling the on-off of each switch module so as to realize the stepless regulation of the load resistor. Stepless adjustment of the resistor can be achieved through the small-capacity water resistor, use and maintenance are convenient, the occupied area is small, cost is low, environmental pollution is small, a control circuit is simple, and pollution cannot be caused to a tes
