parallel circuit‚ then there is less current flowing through that branch. In series‚ a higher developed) resistance will cause more voltage to be dissipated across it. The information-carrying capacity of any telecommunications system is determined by Resistivity: a measure of the the highest frequency that can be practically sent (bandwidth‚ Hz). Series Parallel inherent resistance of the material When sending a DC current‚ electrons will travel all throughout the wire. However‚ V = = = 2= 2
