ESO 3rd. Electricity Activities

Log into Aula Planeta and do these exercises [1] :

There are some mistakes:

• In "Tipos de resistencias". To calculate equivalent resistor in a parallel circuit this formula should be used: 

                          1/R123.. = 1/R1 + 1/R2 + 1/R3+...
                 instead of:

                   R123 = (R1·R2·R3)/(R1+R2+R3)  (Wrong!!)

• La Ley de Ohm. To measure current intensity  an ammeter have to be inserted into the electrical circuit.
