Class Information
Number: 324/691
Name: Electricity: measuring and testing > Impedance, admittance or other quantities representative of electrical stimulus/response relationships > Lumped type parameters > Using resistance or conductance measurement
Description: Subject matter including measuring that property of an object which impedes current and results in the dissipation of power in the form of heat, or the property that is the factor by which the square of an instantaneous voltage must be multiplied to give the corresponding energy lost by dissipation as heat or other permanent radiation.
