Een schakelschema is een visuele weergave van een stroom kring waarbij symbolen worden gebruikt om de componenten en verbindingen weer te geven.
Slide 2 - Tekstslide
Circuit symbols
Slide 3 - Tekstslide
Een serieschakeling heeft één stroompad zonder vertakkingen.
Slide 4 - Tekstslide
Series circuit
Slide 5 - Tekstslide
Serie: one loop; one path.
Parallel:
Branching circuits:
More than one loop
Slide 6 - Tekstslide
One lamp off all lamps off
Slide 7 - Tekstslide
The current is the same in every part of the circuit
Slide 8 - Tekstslide
Voltage in serie circuit
The sum of the voltages across components in series is equal to the voltage of the supply.

Slide 9 - Tekstslide
When we connect components in parallel, the components are connected on different branches of the circuit. There are two or more 'loops’ and multiple paths for a current to flow.

Slide 13 - Tekstslide
1.when current reaches a junction in the circuit, it splits up and some current flows along each route
2. when two branches of a circuit meet, the current combines again
3. the total current flowing through the cell can be found by adding the individual currents flowing through each branch.
Slide 14 - Tekstslide
The voltage across each component is the same.
The current splits up and is distributed over the various components.
