SATHEE: Electrostatics 5 Question 10

Electrostatics 5 Question 10

11. The charge on a capacitor plate in a circuit as a function of time is shown in the figure.

(Main 2019, 12 Jan II)

What is the value of current at $t = 4 s$ ?

(a) $2 μ A$

(b) $1.5 μ A$

(d) $3 μ A$

Show Answer

Answer:

Correct Answer: 11. (c)

Solution:

As we know, Current,

$I = \frac{d q}{d t}$

$=$ Slope of $q$ versus $t$ graph

$=$ Zero at $t = 4 s$ ; (as graph is a line parallel to time axis at $t = 4 s)$
