  6. Voltage divider - Wikipedia

    en.wikipedia.org/wiki/Voltage_divider

    The divider output (V out) appears on the connector adjacent to the cable. A voltage divider can be used to scale down a very high voltage so that it can be measured by a volt meter. The high voltage is applied across the divider, and the divider output—which outputs a lower voltage that is within the meter's input range—is measured by the ...
