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 (10[1])“pull-up” and “pull-down” (10[2])types (10[1]-5[1])of these (10[2])devices. (10[4]-5[4])Rheostats (10[1])and potentiometers (10[4])are variable (10[2])examples (10[3])of these (10[5])circuit (10[3])elements, (10[3])whose strength and tolerance (10[1])are often indicated with a series (10[1])of (10[1])up to six parallel (10[1])colored (10[2])bands. (10[6])An (10[1])ideal (10[2])voltmeter (10[1])would behave as an infinitely strong (10[1])one of these circuit elements, which are usually (10[1])symbolized (10[1])with a jagged line. (10[1])For 10 points, name these circuit elements (10[1])that oppose (10[1])the flow of electrical current. (10[4])■END■
