2 Making Measurements
Resistance (opposition to the current flow) is measured by sending a small
NOTE
current out through the test leads to the circuit under test. Because this current
flows through all possible paths between the leads, the resistance reading
represents the total resistance of all paths between the leads. Resistance is
measured in ohms (Ω).
