Question 136: 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 Q
A
and Q
B
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

Q
A
= ${{CV} \over e}$, Q
B
= ${{VC} \over 2}$

Answer

Q
A
= ${{CV} \over 2}$, Q
B
= ${{VC} \over e}$

Answer

Q
A
= VC, Q
B
= ${{VC} \over e}$

Answer

Q
A
= VC, Q
B
= CV
