The measurement of insulation resistance is carried out by means of a megohmmeter – high resistance range ohmmeter. A general rule-of-thumb is 10 Megohm or more.

In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
