PHY 184 Week 7 Notes-DC Circuits 10/10-10/13 Most practical circuits cannon be resolved into series or parallel systems of capacitors and resistors o To handle this we use Kirchhoff’s rules A Junction is a place where 3+ wires connect o Each connection between 2 junctions is called a branch Each branch has the same current within the branch A Loop in a current is any set of connected wires forming a closed path o You can get back to where you started Kirchhoff’s Junction Rule The sum of currents entering a junction equals the sum of currents leaving the junction Positive terms enter, negative terms exit n i =0 o k=1k Consider a Junction with current i e1tering and i an2 i lea3ing
