Chapter 2, Problem 2.13QAP

Interpretation Introduction

Interpretation:

Using the derived equation, the current passes through the circuit when time flows should be determined.

Concept introduction:

When a voltage source & a resistor are connected with a closed circuit a current flow starts. As the time continues the current flow reduces as the capacitor starts to store the current as electric energy. This reduction in current flow can be determined by the following equation.

$I_{(t)}=I_0{e}^{-\frac{t}{RC}}$

Here,

$\begin{array}{l}{\text{I}}_{\text{(t)}}\text{-Current after t time}\\ {\text{I}}_{\text{0}}\text{-Initial current}\\ \text{t-current flowing time}\\ \text{R-Resistance of the resistor}\\ \text{C-Capacitance of the capacitor}\end{array}$
