Automotive Electrical Systems: Effects of a Rheostat in a Series-Parallel Circuit.
Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.
Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
Effects of a Rheostat in a Series-Parallel Circuit
Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
How Adding Parallel Branches Increases Total Current
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.
