Capacitors, inductors, and resistors are the essential passive components used in electrical and electronic circuits. They are constructed with a variety of materials: ceramics, metals, conductive polymers, and films.
NEW! How much do you REALLY know about film capacitors? They have low ESR and high voltage ratings. Take our 25-question quiz to find out!
Inductors are one of the big three passive components; how much do you know about them? Meet the winners of our Experimenting with Inductors competition. Also, watch The Learning Circuit videos: Inductors & Solenoids, In-depth on Inductors with Kemet part 1, and In-depth on Inductors with Kemet part 2. Take the Inductors Quiz to show how much you've learned, or share your inductors projects/knowledge with us.
Our Polymer Capacitors Campaign includes a quiz, two videos, and a competition. Read all the finishers' experiment blogs, watch our videos, and take the quiz to show how much you've learned about the subject. Or share your polymer capacitors projects/knowledge with us.
Film Capacitors Quiz
Film capacitors have low ESR, efficient capacitance- voltage (CV), and high voltage ratings. But how much do you REALLY know about them? Take our 25-question film capacitors quiz to find out. If you score 100%, we will send you a secret prize. Have fun!
Classical electromagnetic theory explains how electromagnetic forces interact with charges and currents based on a Newtonian model.
Here's the poll question:
In 1820 _________ discovered that when an electric current flows in a conductor a magnetic field is produced. Less than a decade later, ________ established the relationship between current and the magnetic field. In 1831, ________ discovered that a changing magnetic field causes current to flow in a closed electric circuit linked by a magnetic field. _________demonstrated that there is a relationship between a changing magnetic field and the induced current. ________ proved that magnetic poles cannot exist in isolation. In 1865, _______ unified electromagnetism theory in four equations that completely describe the behavior of electric and magnetic fields.
