- Find Zeq here. i already had one solution written to me but it's wrong. my main question is. i know that i do the parallel connection first so 2x2 / 2+2 = 1ohm but what i'm asking is since it's an open terminal is R3,2(parallel resistors) in series to R1? or should i first do R3,2 // to ZL and then add R1 in series?

- Find Zeq here, ignore the semi circle in the wiring i'm just bad at drawing circuits. ZL=JWL write Zeq in terms of JW and give me the final equation. (basically check the parallel and series combinations and give me the final answer.)Will upvote correct answer.

You have been asked to determine theload that will be added to the panelboard that will serve this addition.The addition will be a building 80 ft 3 50 ft. It will consist of four classrooms, every40 ft 3 20 ft and a corridor that is 10-ft wide The following loads will be installed:Each classroom:12 fluorescent luminaires, 2 ft 3 4 ft @ 85 VA each20 duplex receptaclesAC unit, 208-volt, 1-phase @ 5000 VACorridor:5 fluorescent luminaires, 1 ft 3 8 ft @ 85 VA each8 duplex receptaclesExterior:4 wall-mounted luminaires @ 125 VA each4 duplex receptacles 10. The calculated load is__________ VA.11. The connected load is__________ VA.12. The neutral load is_____________ VA.arrow_forwardA 1200-ampere service was installed, consisting of three sets of 600 kcmil THHN/THWN copper conductors per phase. The electrical contractor was careful to cut theconductors the same length. When the utility crew made up the connections at theservice heads, they cut the conductors to different lengths to make their connectionssimpler. The actual lengths of the service-entrance conductors in a given phase ended up being20 ft (6.1 m), 22 ft (6.7 m), and 24 ft (7.3 m). The maximum ampacity of a 600-kcmilTHHN/THWN copper conductor is 420 amperes using the 75°C column of Table310.16. This is more than adequate for the calculated 1200 amperes when three conductors are run in parallel. Determine how the load of 1200 amperes would divide in each of the three paralleledconductors in a phase.arrow_forward
