                                               DEFINITIONS ELECTRICITY:  oppocition to move the electrons. VOLTAGE: the energy to move the electrons. CURRENT: number of electrons inside the circuit. The unit is AMP. RESISTANCE: unit of recistians is OHM. OHM'S LAW: The formula for Ohm's law is V=IR. thats joins voltatge,recistants and intensity. PARALLEL CIRCUIT: two or more components connected in parallel having the same difference of potential across their ends.    SERIES CIRCUIT: when the current goes trught every component in the ciruit. ALTERN CURRENT: DIRECT CURRENT: when the electrons always go straight line.

  In the last class,we went to explain a project of the environmental problem,    this is the result.

                                                                                My carbon footprint is 110% it's a lot,but in a big contry is normal.

Hello I'm Marta Valldeperez Vericat.  In this blog I'm going to explain exercise,videos,and more less.

Only use a mechanism.
