Question 130: Semiconductors and Logic Gates

Question

Two identical capacitors A and B, charged to
the same potential 5V are connected in two
different circuits as shown below at time t = 0.
If the charge on capacitors A and B at time
t = CR is QA and QB respectively, then (Here
e is the base of natural logarithm)

Accepted Answer

In case I diode is reverse biased
Q
A
= CV
In case II, current will flow as diode is forward
biased.
Q
A
= $${{CV} \over e}$$

Answer

QA = $${{CV} \over e}$$, QB = $${{VC} \over 2}$$

Answer

QA = $${{CV} \over 2}$$, QB = $${{VC} \over e}$$

Answer

QA = VC, QB = $${{VC} \over e}$$

Answer

QA = VC, QB = CV
