2)
adjust tlie preset wiper clockwise, until tlie first
voltage
in Table 6.1 is reached,
3)
now set up the breadboard layout of Figure 6.10,
to measure the current through the diode — the bread-
board layout is designed so that all you have to do is
take out a short length of single-strand connecting wire
and change the position of the meter and its range.
Record
the value of the current at the voltage of step 2,
