By Tim Tolbert In this blog post I would like to explain the overall basics of what Inductance is, and how it is used, as I currently understand it to be. What is Inductance? Inductance is the characteristic of an electrical circuit and/or an electrical conductor that opposes the starting, stopping, or a change in value of current. The symbol for inductance is L and the basic unit of inductance is the HENRY (H). One henry is equal to the inductance required to induce one volt in an inductor by a change of current of one ampere per second. Inductance (the characteristic of opposing change) can be found in non-electrical applications as well. For example, anyone who has ever had to push a heavy load (wheelbarrow, car, furniture, etc...) is aware that it takes more work to start the load moving than it does to keep it moving. Once the load is moving, it is easier to keep the load moving than to stop it again. This is because the load possesses the property of inertia. Inertia is
