There are three configuration steps: Put the black probe in the socket labeled “COM” for “common,” meaning it’s common to all measurements. Once it’s there, it’ll never need to be moved. Put the red probe in the socket labeled with the Greek Omega symbol (Ω) for resistance. WebThis resistance serves to limit the amount of current through the circuit with a given amount of voltage supplied by the battery, as compared with the “short circuit” where we had nothing but a wire joining one end of the voltage source (battery) to the other. When the current moves against the opposition of resistance, “friction” is ... porter funeral home of rock valley iowa
