Question

The charge on a capacitor plate in a circuit, as a function of time, is shown in the figure: What is the value of current at t = 4 s ? (A) 3 μA (B) 2 μA (C) zero (D) 1.5 μ A

Tardigrade Admin · Accepted Answer

Since ( dq / dt ) mid t =4 s =0 ∴ current =0

Q. The charge on a capacitor plate in a circuit, as a function of time, is shown in the figure:
What is the value of current at $t = 4 s$ ?

$3 μ$ A

$2 μ$ A

$zero$

$1.5 μ A$

Since $\frac{d q}{d t} ∣ t = 4 s = 0$
$∴$ current $= 0$

Q. The charge on a capacitor plate in a circuit, as a function of time, is shown in the figure: What is the value of current at t=4s ?

3μA

2μA

zero

1.5μA
