Normally, you should pick one of these options and write all of your kcl equations using that option. this will reduce your chances of writing an incorrect equation and can also help you verify that your equations are correct. in this tutorial, however, you will write each kcl equation using a different option each time. you will see that the options are equivalent. first, write the kcl equation at the node labeled \(v_1\) by setting the sum of all of the currents leaving the node to zero. express your answer in terms of \(v_1\), \(v_2\), and \(v_3\). make sure each term is expressed in amperes.
