1. The problem statement, all variables and given/known data Determine the Req, IT, and the current and voltage across each resistor. Collapse each drawing into one resistor that equals Req. Find the total power used by the circuit. Also determine the voltage, current, and power for each individual resistor. The one I'm having trouble with: 2. Relevant equations Req = R1+R2+R3... 1/Req = 1/R1+1/R2+1/R3... V = IR P = IV 3. The attempt at a solution I combined B and C into BC (4 Ω) and then combined that with F to make BCF (2 Ω). This would give me the following resistances: RA = 2 Ω, RE = 6 Ω, RBCF = 2 Ω, RG = 2 Ω, and RD = 5 Ω. That would make Req = 17 Ω since all these are now in series. When trying to calculate the current of the whole circuit... I = V/Req = 40/17 = 2.35 A My teacher posted that the total current should be 4 A. I'm not sure where I messed up.
