DO IN MATLAB: The following diagram shows a RL series circuit where a resistor and an inductor is connected in series.The current and the voltage in the circuit above are related by the following differential equationRi$+$L di$/$dt$=$v where i is the current through the circuit $($in Amperes$)$ and v is the voltage drop across the resistor and the inductor $($in volts$),$R is the resistance $($in Ohms$)$ and L is the inductance $($in Henry$).$ You can assume that these units are consistent with each other, and so you don't need to consider them.Initially the switch is turned off so that there is no current flowing in the circuit. At t$=0,$ the switch is turned on$.$ When the switch turns on$,$ the current will build up from zero to some steady state $($constant$)$ value. a$)$If $=6$v $($volts$),=80($ohms$)$ and $=110$ H $($henry$),$ find the current $($in amperes$)$ at $11$ seconds, using Heuns method with a step size of $0\mathrm{.}1$ seconds. Give your answer correct to $4$ decimal places. b$.$ Find fhe final steady state current vallue ib amperes
