Inductor (Electrical Engineering)

An inductor is a transient circuit component that stores energy in the form of magnetic flux, and allows an induced voltage to be created. It can be considered as a counterpart to a capacitor

Key Formulas §

Voltage

$$V(t)=L\frac{\text{d}I}{\text{d}t}$$

Note

• $V$ = Voltage (in $V$)
• $L$ = Inductance (in Henrys, $\text{H}$)
• $\frac{\text{d}I}{\text{d}t}$ = Change in Current (in $\text{A/s}$)

Applications §

• Spark plugs
