When an ohmmeter is used to test a diode, as in Figure, a very low resistance (but not zero) in
one direction means that the diode is: OPEN OR SHORTED OR FORWARD BIASED OR REVERSE
BIASED?
In the two figures, the measured diode barrier potential is approximately:
0.3 OR 0.6 OR 0.9 OR 1.2?

If the 10-0 resistor in Figure (C) is charged to 100 N and the oscilloscope vertical sensitivity is 0.5
v / division, then the vertical axis, in terms of Current, is: 0.5mA/div or 5mA/div or 50mA/div
