For a diode, at 10mA DC resistance is 70Ω. The voltage corresponding to 10mA will be ________

A)
0.5V
B)
0.6V
C)
0.7V
D)
0.8V

Correct Answer : Option (C) :   0.7V

Explanation : Static or DC resistance is the resistance of a diode at its operating point.
Resistance = voltage/current
Therefore, voltage = current x resistance = 10mA x 70 = 0.7V
