- a) Write an equation for the currents entering in/out of the top junction in Figure 1. Use I1 as the current coming from the left, I2 as the current going downward, and I3 as the current going to the right. b) You can draw three loops in order to solve this circuit. Write the corresponding voltage equations for these loops in terms of V1, V2, VA, and VB; where VA and VB are voltages across the resistors RA and RB respectively. c) Using Ohm's law combined with the equations you found above; express I1, I2, and I3 as equations in terms of the know quantities V1, V2, RA, and RB. d) Now you have all the information you need to express VA and VB as equations in terms of V1, V2, RA, and/or RB.arrow_forwardConsider the following circuit diagram.
