Parallel Ciruits 5

Chapter 5

Branch One current path in a parallel circuit
Current Divider A parallel circuit in which the currents divide inversely proportional to the parallel branch resistances
Kirchhoff's Current Law A law stating that the total current into a node equals the total current out of the node. Equivalently, it can be stated that the algebraic sum of all the currents entering and leaving a node is 0
Node A point or junction in a circuit at which two or more components are connected
Parallel The relationship between two circuit components that exists when they are connected between the same pair of nodes
Total Parallel Resistance 5-1 RT = 1÷ 1/R1 + 1/R2 + 1/R3 + ... 1/Rn
Special Case for Two Resistors in Parallel 5-2 RT = R1R2 ÷ R1 + R2
Special Case for n Equal-Value Resistors in Parallel 5-3 RT = R ÷ n
Kirchhoff's Current Law 5-4 Iin(1) + Iin(2) + Iin(3) + ... Iin(3) = Iout(1) + Iout(2) + Iout(3) + ... Iout(m)
General Current-Divider formula 5-5 Ix = (RT ÷ Rx) IT
Two-Branch Current-Divider Formula 5-6 I1 = (R2 ÷ R1 + R2) IT
Two_Branch Current-Divider Formula 5-7 I2 = (R1 ÷ R1 + R2) IT
Total Power 5-8 PT = P1 + P2 + P3 + ... Pn
