A circuit with two batteries, Emf1 and Emf2, and three resistors, R1, R2, and R3 is shown in the diagram. Currents I1, I2, and I3 flow through each of the resistors, respectively. R1 R2 R3 Emfi Emf2Determine the value of Emfg such that no current flows through resistor R2. Your answer should be in terms of the other known quantities given in the problem ('3me R1, R2, R3, I1, I2, I3). Your solution process here must be consistent with the loop and node equations you wrote in the previous part
