... to ground through a coiled retractable cable and 1 megohm resistor, which allows high-voltage charges to leak through but prevents a shock hazard when working with low-voltage parts ... Where higher voltages are present, extra resistance (0.75 megohm per 250 V) is added in the path to ground to protect the wearer from excessive currents this typically takes the form of a 4 megohm resistor in the ...

... connect to oscilloscopes with a matched 50 ohm (rather than 1 megohm) input impedance ... (for 20× attenuation) series resistor (rather than the 9 megohm resistor of the 10× probe) ... High-impedance scope probes are designed for the conventional 1 megohm oscilloscope, but at high frequencies mismatch between the scope input impedance and the cable impedance presents a transmission line ...
