17. Impedance w Definition: a general measure of how a circuit affects the current through it. w Impedance = resistance + reactance w Impedance is used to refer to the behavior of circuits with resistors, capacitors and other components. w In a resistive circuit, impedance=resistance.

18. Equipment Impedances w Each measuring device changes the circuit when you use it. w The impedance of the device helps you understand how much. w Device Impedances Function Generator: 50 ohms ‘Scope: 1Meg ohms DMM (DC voltage): 10Meg ohms DMM (AC voltage): 1Meg ohms DMM (DC current): 5 ohms (negligible)
