MATLAB code:

When a resistor $($R$),$ capacitor $($C$)$ and battery $($V$)$ are connected in

series, a charge $(Q)$ builds up on the capacitor according to the

formula:

$Q(t)=CV(1-e^{\frac{-t}{RC}})$

If there is no charge on the capacitor at time $=0.$ You want to monitor the

charge on the capacitor every $0\mathrm{.}1s$ in order to detect when it reaches a

level of $8$ units of charge. Using $V=9,R=4$ and $C=1,$ write a program

that calculates the time and charge every $0\mathrm{.}1$ seconds until the charge

first exceeds $8$ units.

Once you have done this, rewrite the program to display the charge

only while it is strictly less than $8$ units.

Your program should include a relevant plot.
