Physics 1260 Exam 2 questions and answers well explained. Circuits - correct path along which electrons can flow from the negative terminal to the positive terminal is Series Circuit - correct a single pathway for electron flow between the terminals of the battery, generator, or wall outlet Parallel Circuit - correct branches, each of which is a separate path for the flow of electrons Series Characteristics - correct answers.-electric current through a single pathway -total resistance to current is the sum of individual resistances -current is equal to the voltage supplied by the source divided by the total resistance of the circuit -the voltage drop across each device are proportional to its resistance -if one device fails, current in the entire circuit ceases Parallel Characteristics - correct answers.-voltage is the same across each device -the total current in the circuit divides among the parallel branches, the amount of current in each branch is inversely proportional to the resistance of the branch -the total current in the circuit = the sum of the currents in its branches -as the number of parallel branches is increased, the overall resistance of the circuit is decreased -a break in one path does not interrupt the flow of charge in the other paths Magnetic Poles - correct rise to magnetic force (two types: N and S) Rules for Magnetic Forces b/w Magnetic Poles - correct answers.-like poles repel; opposites attract -in all magnets--can't have one pole without the other -no single pole known to exist Series and Parallel - correct its are connected in what two common ways?
