3. SERIES CIRCUITS
The same wire, no branches.
Adding more bulbs to a simple circuit will make the bulbs darker.
In a series circuit, if a bulb blows, the other components stop working.
Vocabulary:Wire= cable
Branches= ramas
Darker= más oscuro
Blow= fundirse

EXERCISE D: SERIES CIRCUITSDesign the following circuits by using
1.) Series Circuit with one light bulb, switch, and 4.5 V cell.
2.) Series Circuit with 2 bulbs:
3.) Series Circuit with 3 bulbs:

1. What is a series circuit?
2. What happens when you add more bulbs in a circuit and the battery has the same power?
Vocabulary:Brightness= brilloSeries Circuit= circuito serieBulb= bombillaSwitch= InterruptorVolts= voltios (unidad de medida de la
energía potencial de las pilas o baterias

4. PARALLEL CIRCUITSDifferent wires, some branches.
In a parallel circuit, if a bulb blows , the other components keep working.
The bulbs stay bright if you add more bulbs in parallel.
Vocabulary:Wire= cable
Branches= ramas
Bright= brillar
Keep= mantener

EXERCISE E:PARALLEL CIRCUITSDesign the following circuits by using
Crocclip.exe
1. What is a parallel circuit?2. What is an advantage of a parallel circuit?3. What happens to the brightness of the light bulbs in a parallel circuit when another light bulb is added?
1) Parallel Circuit with 2 bulbs and a 4.5 Volts battery.
2) Parallel Circuit with 3 bulbs and a 4.5 Volts battery
Vocabulary:Parallel circuit = circuito paraleloVolts= voltios (unidad de medida de la energía potencial de las pilas o baterias)Add= sumar, añadirBrightness= brillo
