Quizplus · Accepted Answer

The time constant ($\tau$) of an integrating circuit is given by the product of the resistance and capacitance, $\tau= R \cdot C$. Substituting the given values, we get:
$\tau= 47 \mathrm{k\Omega \cdot 0.01 \mu F} = 0.47 \mathrm{ms}$

Therefore, the answer is B, 0.47 ms.
