WebJul 22, 2024 · Clamp the meter near the ground rather than at the top of the rod. 3. Turn on the meter. How you start the meter depends on the specific brand you have. Some simply have a button that says "power" or "on." [5] Others have a dial that needs to be set to ohms. 4. Check the resistance reading on the meter. WebOct 6, 2024 · Add a comment. 1. In general, you use a power supply to run a known current through the wire, and measure the voltage drop using a voltmeter accurate to the mV level. Then you use Ohm's law to calculate the resistance. V = I * R. V is the voltage on the voltmeter, I is the current, and R is what you want to know.
WebInsulators: Materials that present high resistance and restrict the flow of electrons. Examples: Rubber, paper, glass, wood and plastic. The higher the resistance, the lower the current flow. If abnormally high, one possible cause (among many) could be damaged conductors due to burning or corrosion.

WebWe do not want the voltmeter to load the circuit. Consequently an ideal voltmeter will have infinite resistance. An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit. We will find the shunt as part of the ammeter circuit.
