Question

They’re not audio devices, but types of these devices that have layers arranged in a criss-cross formation reduce the proximity effect and are named for their resemblance to basket-weaves and spiderwebs. When operating at low frequency, these devices may possess a laminated core, whereas at high frequency, they may possess a ferrite core. Examples of these devices that emit less electromagnetic interference are torus-shaped. (10[1])Because the voltage across these devices is proportional to the second time derivative of charge, (10[1])one of these devices is paired with a capacitor (10[1])to form (10[1])an oscillating circuit. (10[1]-5[1])Two of these devices with differing numbers of coils are used to create transformers. (10[2])For 10 points, name these circuit components (10[1])that store energy in a magnetic field and may consist of a solenoid. ■END■ (10[1])

ANSWER: inductors [accept chokes; prompt on electromagnets; prompt on wire coils or solenoids until read; prompt on transformers by asking “what devices are they constructed from?”]
