The Power Loss Due to Wire Resistance computes the power loss due to the resistance (R) of a wire.

INSTRUCTIONS: Choose your preferred units and enter the following:

(R) This is the resistance in the wire.
(l_rms) This is the DC current

Power: The calculator returns the power loss in watts. However, this can be automatically converted to other power units via the pull-down menu.
