Beginner''s Corner: Inductors in DC Circuits
Introduction In this installment we examine inductors (also called coils) and their behavior in DC circuits. We''ll look at what they are, what they do, and how they respond in both steady state and transient conditions (i.e. a state change). In addition to the theory, we''ll spend some time in the lab looking at real-world … Continue reading Beginner''s …
What does a capacitor do in a DC circuit?
Which capacitors are used in DC circuits applications? The correct answer is ''option 4''.

How does a capacitor block DC?
I think it would help to understand how a capacitor blocks DC (direct current) while allowing AC (alternating current).. Let''s start with the simplest source of DC, a battery: When this battery is being used to power something, electrons are drawn into the + side of the battery, and pushed out the -side. Let''s attach some wires to the battery:
