Different voltages are applied across a 
junction and the currents are measured for each value. Which of the following graphs is obtained between voltage and current?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
junction has low resistance in one direction of potential difference 
, so a large current flow (forward biasing). It has a high resistance in the opposite potential difference direction 
, so a very small current flow (reverse biasing).
