Radio-frequency types of these devices can be made with the Ayrton-Perry winding method. The MELF type of these devices are used over normal surface mount examples of them when higher performance is needed. Preventing floating pins from appearing on a microcontroller can be accomplished with the “pull-up” and “pull-down” types (10[1])of these (10[1])devices. Rheostats and potentiometers (10[4])are variable examples of these (10[1])circuit elements, whose strength and tolerance are often indicated with a series (10[1])of up to six parallel colored (10[1])bands. An ideal voltmeter would behave as an infinitely strong one of these circuit elements, which are usually symbolized with a jagged line. For 10 points, name these circuit elements that oppose the flow of electrical current. ■END■
