In an inductor, it equals the inductance times the time derivative of current.
Op-amps convert a small amount of this quantity into a larger amount of it. In an inductor, it equals the inductance times the time derivative of current. In circuit diagrams, sources of one form of this quantity are represented by a short line adjacent and parallel to a longer line. The integral form of Faraday's law determines the amount of this quantity generated by changing magnetic flux. When the E-field is irrotational, or conservative, its negative gradient is the electric field. For 10 points, name this quantity which measures electric potential energy per unit charge, and which is related to current and resistance by Ohm's law.
Op-amps convert a small amount of this quantity into a larger amount of it.
