What Determines the Frequency of an Inductor?
Description An inductor is a wire coil. When an electric current flows through an inductor, a magnetic field forms around it. How much magnetism forms depends on the number of turns or loops in the coil, and other details. The Henry Inductance is measured in units called henries. An inductor of one henry will produce a voltage difference of one volt across its leads when current is changing at the rate of one ampere per second through it. Lenz’s Law The magnetism produced by the inductor momentarily resists the flow of current. This is called Lenz’s Law and results from electrical energy changing to magnetic energy and back again. Frequency Signals flow through an inductor in inverse relation to their frequency. Low frequencies and DC flow easily; high frequencies become increasingly blocked, according to Lenz’s Law. Reactance The property of blocking signals by an inductor is called reactance. Reactance is similar to resistance, except it’s frequency-related. The following formula det
