An inductor is a device created specifically for its inductive properties. Their capacity is measured in henries, which is when a change of one amp per second yields a voltage differential of one volt across the device. Real, or non-ideal, inductors have a small amount of capacitance and resistance as well but those properties can arguably be ignored most of the time. However, if your circuit isn’t responding the way you anticipated, those may not be so negligible. Inductors are typically used to absorb high frequency signals or adjust the resonant frequency of a circuit.
It consists of a coil of conducting wire.
