Inductance Formulas

• Voltage-Current Relationship
  • $v_L(t)=L\frac{d{i}_L(t)}{dt}$
  • $i_L(t)=\frac{1}{L}\int v_L(t)dt$
• Energy Stored in a conductor
  • $W_L=\frac{1}{2}L{i}_L^2$
• Inductor in Series
  • $L_{eq,series}=L_1+L_2+\dots$
• Inductors in Parallel
  • $\frac{1}{L_{eq,parallel}}=\frac{1}{L_1}+\frac{1}{L_2}+\dots$
