5) resistor currents are directly proportional to the circuit currents.more the current flowing in the circuit ,more will be the current flowing the resistors.

6) as per the property of the resistors(i.e.. which resists the free flow of current),the resistor currents are inversely proportional to the value of the resitance ...

7)currents in the wires are same as the currents in the resistors........provided same conditions.....this is because a practical wire is a long continuous linear resistor for a given material,length,area of cross section ...

8)currents in the series circuit is same through all the resistors because there is no alternative path for the current to flow ..//but in case of the parallel circuits the current has alternative paths,so currents will flow more through less resitance paths ..........hence considering the currents in resistors of series and parallel circuits ,the current flow is different...
