Uva Virtual Lab: Bulbs in Series and Parallel

Emerging electricians extend mental models of light bulbs and resistors in series and or in parallel circuits to include the connection of photovoltaic cells in arrays. They investigate open circuits, using a DC voltmeter, a light...

Here's a video that explains the difference between series and parallel circuits, including the impacts of each on current and voltage.

Look at adding an identical bulb to a circuit of a cell and a bulb. In this circuit the two light bulbs are in parallel to each other.

Mislabeled bottles can cause a dangerous situation! Young chemists design a method for determining the true contents of a solution in a virtual lab activity. Their study of density helps them identify the makeup of the solution.

Textbook problems with a twist! Young chemists analyze an ionic reaction to identify the limiting reagent. They then make calculations to determine the concentration of unknown solutions. Finally, they put their work to the test and...

Review how to find the equivalent resistance for resistors in parallel and series configurations. Recall the current and voltage properties of series and parallel configurations of resistors.

This source describes a water flow analogy of two batteries in series as a two-stage gerbil powered waterwheel. Check out the video clips.

What happens to the enthalpy of a reaction as the concentration of reactants varies? Learners explore this question with a virtual lab activity. They consider five different solutions of the same reactants and monitor the temperature...

Build an understanding of electrical circuits in series and parallel. The video instructor demonstrates the effects of manipulating both a series and parallel circuit. Learners realize the difference between the types of circuits as well...
