We can see how circuits work, and represent them with some simple diagrams, using basic electrical components like these. You start with a cell, or combination of cells. These could be batteries ...

When a switch is closed (on) it makes the circuit complete and electricity can travel around the circuit. If you add more cells to a series circuit, there will be more electrical energy to go ...

Electricity powers nearly everything we use daily, but what is it really? In this video, we unravel the true nature of electricity, explaining it in simple yet fascinating terms. At its core, ...

The protons get sucked across a ‘proton exchange membrane’ (PEM), while the electrons – unable to cross the PEM – get sent through a circuit ... and fuel-cell electric vehicles (FCEVs).

In this course, you will learn the purpose of each component in an equivalent-circuit model ... to use them to simulate cell behaviors under different load profiles. Prior knowledge needed: ECEA 5730, ...

The result: not only do secondary school students gain a better conceptual understanding of electric circuits, but teachers also perceive the curriculum as a significant improvement in their teaching.
