3. Measuring DC and AC voltages using resistive dividers

3.1 Voltage measurement

The first version of a resistive divider is shown in figure 19 . It includes the two resistors R H and R B of the divider, a voltmeter V and, in parallel with the latter, a device P used to protect the measuring device in the event of breakdown at R H .
