§4-3 Inductance and capacitance combinations The inductance which is equivalent to several inductance connected in series is simply the sum of the series inductance. The series combination of N inductors: Leq = L1 + L2 ++ LN L1 2 LN L Leq

The parallel combination ofN inductors: L13L2 L,+L 1/Lm=l/L1+1/L2+…+1/LN Inductance in parallel combine exactly as do resistors in parallel

The parallel combination of N inductors: Inductance in parallel combine exactly as do resistors in parallel. ( ) 1 2 1 2 L L L L Leq + = Leq L L LN 1/ 1/ 1/ 1/ = 1 + 2 ++ L1 L2 LN Leq

The series combination of n capacitors C+C 1/Ca=1/C1+1/C2+…+1/CN Capacitance in series combine exactly as do resistors in parallel. The parallel combination of N capacitors: CI C=C1+C,+…+C Capacitance in parallel combine exactly as do resistors in series

The series combination of N capacitors: Capacitance in parallel combine exactly as do resistors in series. ( ) 1 2 1 2 C C C C Ceq + = Capacitance in series combine exactly as do resistors in parallel. The parallel combination of N capacitors: Ceq C C C N 1/ 1/ 1/ 1/ = 1 + 2 ++ Ceq = C1 + C2 ++ C N C1 C2 CN Ceq C1 C2 CN Ceq
