Inductors and Inductance

Inductors are components in electrical circuits that store energy in a magnetic field. Inductance is the measure of an inductor's ability to store energy.

Inductance Formula

The formula for inductance is:


V = L * (dI/dt)

Where:

  • V is the voltage (in volts)
  • L is the inductance (in henrys)
  • dI/dt is the rate of change of current (in amperes per second)

Understanding Inductors

Inductors consist of a coil of wire that creates a magnetic field when current flows through it. The magnetic field stores energy, which can be released when the current changes.

Example Calculation

Consider an inductor with an inductance of 2 henrys and a current change rate of 3 amperes per second:


V = L * (dI/dt)
V = 2H * 3A/s
V = 6V

Applications of Inductors

Inductors are used in:

  • Filtering signals
  • Storing energy
  • Transformers
  • Power supplies

Practice Problems

  1. Calculate the voltage across an inductor with an inductance of 3 henrys and a current change rate of 4 amperes per second.
  2. Determine the inductance of an inductor with a voltage of 5 volts and a current change rate of 2 amperes per second.
