In a series circuit Electrons flow along a single path through 2 or more loads before returning to source. Law #1 - any break in a series circuit stops the entire electron flow (a break or loose connection can prevent electrons from flowing) Law #2 - when there are two or more loads in a series circuit, the voltage drop across each load is a fraction of the total voltage supplied by the source voltage across each load …

…I1 = V/R1 I2 = V/R2 I3 = V/R3 IT = I1 + I2 + I3 + ... Law #4 - The total resistance in a parallel circuit decreases as the number of loads or individual resistances increases. The total resistance is less than that of the smallest single resistance. All branches act as one broad pathway which offers less resistance to the flow of electrons than any single pathway. 1/RT = 1/R1 + 1/R2 + 1/R3 + ... or RT = ( R1 x R2) / (R1 + R2)
