When mass-market digital meters arrived in the 1970s they incorporated FET input stages, so immediately there was the possibility of a multimeter with an impedance in the mega ohms rather than the ...

Turn the multimeter's selection knob to ohms. Plug the black probe wire into the common port. Plug the red probe wire into ...

The resistance is then presented in ohms. Because different electrical circuits can have vastly different resistances, there ...
