The little schoolhouse with its flagpole on top and its two doors in front, one for boys and the other for girls, stood on the crest of a hill, with rolling fields and meadows on one side, a stretch of pine woods on the other, and the river glinting and sparkling in the distance.
An ohmmeter is a device that measures the amount of electrical friction generated as electrons pass through an electrical conductor.
You can measure resistance of an electronic circuit using an ohmmeter, which is a standard feature found in most multimeters. The procedure is simple: First, you disconnect all voltage sources from the circuit; then, you touch the ohmmeterâs two probes to the ends of the circuit and read the resistance (in ohms) on the meter. Resistance is measured in units called ohms, represented by the Greek letter omega (Ï). The standard definition of one ohm is simple: Itâs the amount of resistance required to allow one ampere of current to flow when one volt of potential is applied to the circuit.
