Required information
The charge entering the positive terminal of an element is q = 4 sin(4 To mC, while the voltage across the element

Expert Solution

Step 1

Given data,

Charge is $\begin{array}{rcl} q \end{array} \begin{array}{rcl} = \end{array} \begin{array}{rcl} 4 \end{array} \begin{array}{rcl} \sin \end{array} \begin{array}{rcl} (4 πt) \end{array} \begin{array}{rcl} \end{array} \begin{array}{rcl} mC \end{array}$
Voltage is $v = 9 \cos (4 πt) V$
Time is t = 0.3 s

Expression of current with respect to charge,

$i (t) = \frac{d q}{d t} i (t) = \frac{d (4 \sin (4 πt))}{d t} i (t) = 40 πcos (4 πt) mA$
