A circuit has a 24V source, and three resistors: R1 = 8Ω (series with source), R2 = 12Ω and R3 = 6Ω in parallel. Apply KCL and KVL.
Formula Sheet
KCL: ΣI_in = ΣI_outKVL: ΣV_loop = 0V = IRWhat is the equivalent resistance of R2=12Ω and R3=6Ω in parallel?
Total resistance = R1 + Rp = 8 + 4 = 12Ω. What total current flows from the 24V source?
By KCL, voltage across parallel combination = I × Rp = 2 × 4 = 8V. What current flows through R3 (6Ω)?
KVL states that the algebraic sum of voltages around any closed loop is:
