1. The problem statement, all variables and given/known data Assume that I = 22mA , V = 6.0V , and R = 350Ω. Determine the current between B and D using the superposition principle. 2. Relevant equations V=IR Superposition Principle G=1/R Voltage and Current dividers KCL, KVL 3. The attempt at a solution I_BD = I_BD' + I_BD'' Shorting the voltage source first, I have: R_eq of resistors now in parallel = 100*300/(100+300) = 75 Applying the current divider to the remaining circuit, I have: I_BD'' = -0.022 * 300/825 = -0.008 (I also solved this using mesh analysis and got the same answer) Now replacing the current source with an open circuit, I have: R_eq from A to C to D to B = 750 Combining that with the 300 Ohm resistor it is now in parallel with, then with the 100 Ohm resistor in series, I have: R_eq = 314.3 Solving for total current with V=IR, I_total = 0.019 A Applying the current divider: I_BD' = 0.019*300/1050 = 0.0054 A Combining I_BD' and I_BD'', I_BD = -0.0026 A which is incorrect. Not exactly sure what I'm doing wrong here.
