WebStep 3: Make a Resistor. To better understand how resistors work, let us make our own resistor. All we will need is a pencil (a #2 will do fine, but a 6B is better), a sheet of paper, and some paperclips. Take a 6" x 9" envelope and turn it sideways, and then rub a pencil back and forth along the edge. WebHence, a standard resistor is a device that goes against the flow of electrical current. So, if a resistor’s standard values are high—they will oppose current flow more. And the unit values for resistors are in ohms. With that in mind, you can proceed to understand standard resistor values.
