Document Summary

When elements are connected end-to-end, we say they are connected in series and are in series if no other path is connected to the node between and. Ki(cid:396)(cid:272)hhoff"s cu(cid:396)(cid:396)e(cid:374)t la(cid:449) i(cid:373)plies that all ele(cid:373)e(cid:374)ts i(cid:374) a se(cid:396)ies (cid:272)i(cid:396)(cid:272)uit ha(cid:448)e ide(cid:374)ti(cid:272)al (cid:272)u(cid:396)(cid:396)e(cid:374)ts. Problem: identify the groups of circuit elements that are connected in series. A and b are in series & e, f, and g are in series a) b) c) Given that = 3a and = 1a, determine the values of and. Circuit concepts and diagrams page 1 e) f) Two or more circuits elements are said to be connected in parallel if both ends of each element are directly connected to corresponding ends of every other element.
