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!
Downsizing MLCCs Quiz
Do you know how to optimize design with smaller capacitors? Take our quiz to see how much you know. Also check out our WorkBench Wednesdays 30th episode and the MLCC Q&A interview video with Murata.
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.
