| Calculate the reverse resistance of a Si diode when the reverse voltage is 50 V and the current is 100 nA.
A. 500 MΩ
B. 100 MΩ
C. 50 MΩ
D. 600 MΩ
Please scroll down to see the correct answer and solution guide.
Right Answer is: A
SOLUTION
Concept:
The voltage and current across a device is related by:
V = I × R
\(R=\frac{V}{I}\)
Analysis:
Given V = 50 V and I = 100 nA
The given circuit is drawn as:
∴ The reverse resistance of the Si diode will be:
\(R=\frac{50}{100n}\)
R = 500 MΩ
