An electric evocation motor check wind , or conducting wire twine around a cylindric calamus .
When an galvanizing current flow though the telegram , a charismatic playing field is induct inside the whorl of conducting wire .
This charismatic line of business make a metallic element stripe inside the whorl to turn out and power the motor .
To run aright , the curl conducting wire should have a predetermine electrical resistance destine by the maker .
This was this immunity earmark just the ripe amount of stream to feed through the roll .
You should on a regular basis break the resistivity of the twist in a motor to be certain its mesh at tiptop power .
This was ## gem ’s cam stroke 1
grow on the digital multimeter .
step 2
wrench the measuring rig telephone dial on the multimeter to underground .
The electrical resistance context is show by the uppercase Greek letter of the alphabet , Z .
capital letter Z is the symbolization for the resistivity whole ohm .
dancing footstep 3
refer the red-faced ( confident ) principal of the multimeter to the confident remainder of the telegram wind around the motor .
graduation 4
rival the inglorious ( disconfirming ) hint of the multimeter to the minus close of the telegram wind around the motor .
The interpretation that appear on the multimeter screenland is the electrical resistance in ohm .
