Imagine life without your favorite electronic devices! Use this guided-inquiry lab activity to investigate the essential function of resistors in modern electronics. In this two-part “mystery” analysis, students first decode the color bands on a series of nine unidentified resistors to predict their resistance values. They then test their predictions by placing the resistors in series and parallel circuit combinations and measure the current and voltage. Students see how resistors help control the current to circuit components and split voltage to bring power to multiple components. Versatile and very affordable activity connects concepts and applications and will fit in any electricity unit.
