ELECTRIC CIRCUITS

On these days, we have been working on doing some electric circuits, such as: parallel and series circuits.

In parallel circuits we have used a battery 4.5V and resistors of 220Ω and three LEDS, one was red, the other was green and the other was yellow.

In series circuits we have used a battery of 9V, because with the battery of 4.5V, we didn´t have enough volts. We have also used three resistors of 220Ω and three LEDS, with the same colours.

We have observed that in parallel circuits, if you take out one resistor and one LED, it works, but in series circuits, it doesn´t work.

Here we leave you a photo of the series circuit we have done:
