Laplace transforms: R series with RC parallel circuit

Problem Statement

Find the Voltage across the capacitor for t>=0:

Voltage across capacitor at t(0-)=0

$v(t0)=0Volts$

$v(t)=10Volts$

$R_{1}=20{\boldsymbol {\Omega }}$

$R_{2}=30{\boldsymbol {\Omega }}$

$C=.1Farad$

Loop 1

$v(t)=R1(i_{1}+i_{2})+R2(i_{1})$

$10=20(i_{1}+i_{2})+30(i_{1})$_______________________________________equation (1)

Loop 2

$v(t)=R1(i_{1}+i_{2})+{\dfrac {1}{C}}\int {i_{2}dt}$

$10=20(i_{1}+i_{2})+{\dfrac {1}{0.1}}\int {i_{2}dt}$_______________________equation (2)

Solving equations (1) and (2) simultaneously

Laplace Transform S-domain

Inverse Laplace transform T-domain
