Automotive Electrical Systems: Effects of a Rheostat in a Series Circuit
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied.
Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
In this interactive and animated object, learners examine Midtronics hand-held battery and charging system testers and view the operation of these testers in an automotive repair facility.
