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 of these devices. (10[1]-5[1])Rheostats and potentiometers are variable (10[1])examples (10[1])of these (10[2])circuit (10[1])elements, (10[2])whose strength and tolerance are often indicated with a series of up to six parallel colored 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 (10[1])the flow of electrical current. (10[1])■END■
