Series circuits: , The current is the same at all points in this circuit, I1 = I2, The potential differences around the circuit add up to the potential difference of the supply., The total resistance of a number of resistors in this circuit is equal to the sum of all the individual resistances, Rtotal = R1+ R2, Adding a resistor increases the total resistance because electric charge has to pass through another component., The current through a resistor in this circuit is I=V/R, Parallel circuits: , The currents in the branches of this circuit add up to the supply current, Itotal = I1+I2, When resistors are connected in this circuit, they have the same potential difference across them., The total resistance value will always be less than the smallest individual resistor in the combination., Adding a resistor would decrease the total resistance because you are providing an alternate path for the electric charge.,
