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