PARALLEL CIRCUIT

The parallel circuits have the same voltage. The total intensity (current) is the sum of the currents through the individual components. We can find the intensity according to the Ohm's law. To find the resistance sum all the resistances.

SERIES CIRCUIT

Last day, we have done a series circuit.
Firts we connected all thhe positives and then all the negatives. We connected to the battery and the bulbs started lightning.
We had a problem, one bulb didn't work so we had to change, because if one bulb doesn't work the other bulbs neither.
In a series circuit the intensity is the same.
