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. (-5[2])Rheostats and potentiometers are variable (10[1])examples of these circuit elements, whose strength and tolerance are often indicated with a series of up to six parallel colored bands. (10[2])An ideal voltmeter would behave as an infinitely strong (10[1])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. (10[1])■END■
