Inductors and Inductance: An Explanation

Formula - 1 (Faraday's Law)

Where,

•  is Induced voltage/Potential Difference, in Volt
•  is Number of turns of the Coil
•  is Magnetic Field of the Coil, in Tesla
•  is Cross-sectional Area of the Coil, in Square Meter
•  is Time Constant, in Second

Formula - 2 (Magnetic Field of a Coil)

Where,

•  is Magnetic Field of the coil, in Tesla
•  is Permeability Constant, 4π × 10-7 Tesla·Meter/Ampere (=1 Henry/Meter)
•  is Number of turns of the Coil
•  is Current, in Ampere
•  is Length of the coil, in Meter

Formula - 3 (Inductance of an Inductor)

Where,

•  is the Inductance of the Coil, in Henry
•  is Permeability Constant, 4π × 10-7 Henry/Meter (Henry/Meter=Tesla·Meter/Ampere)
•  is Number of turns of the Coil
•  is Cross-sectional Area of the Coil, in Square Meter
•  is Length of the coil, in Meter

Formula - 4 (Self Induced Voltage of an Inductor)

Where,

•  is the self-induced Voltage of the Inductor, in Volt
•  is Inductance of the Coil, in Henry
•  is Current, in Ampere
•  is Time, in Second

Formula - 3(a) (Inductance of an Inductor)

Where,

•  is Inductance of the Coil, in Henry
•  is the self-induced Voltage of the Inductor, in Volt
•  is Current, in Ampere
•  is Time, in Second
