This open hands-on model building effectively combines theoretical and practical STEM skills. Analogies are ideal in supporting and complementing this practical model making and reinforcing the principles taught.
A circuit or wiring diagram is a visual display of an electrical circuit.
The electrons enters from a point to an electrical circuit which is called the “source” of electrons or “electrons source” . The point where electrons leaves the circuit is called ground or earth(in some concepts it is also know as “return”).
Resistors and other circuit elements can be connected in series or in parallel. Resistance in series circuits is the sum of the resistance.
