A car maker needs an \(R C\) timing circuit to trigger the windshield wiper relay. The circuit should be driver selectable to trigger at \(1,2,5\), and \(10 \mathrm{~s} \pm 5 \%\). The source circuit is the car voltage of \(12 \mathrm{~V}\) with a series resistance of \(10 \Omega\). You must use standard parts (see Appendix G ). You have a single-sided OP AMP available with a \(V_{\mathrm{CC}}\) of o V and \(+12 \mathrm{~V}\) that you can use to trigger the windshield wiper relay. The relay triggers with an input of \(+12 \mathrm{~V}\) \(\pm 1 \mathrm{~V}\). You may assume that the circuit resets after the trigger. You should validate your design using Multisim.
