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? PLEASE READ THIS. and solve properly. EXPLAIN WHAT I ASKED PROPERLY. UPVOTE WILL BE GIVEN.
The E-field pattern of an antenna, independent of o, varies as follows:
E =
0
7100
0° ≤0≤45°
45° < 0 ≤ 90°
90° < 0 ≤ 180°
(a) What is the directivity of this antenna?
(b) What is the radiation resistance of the antenna at 200 m from it
if the field is equal to 10 V/m (rms) for 0 = 0° at that distance and
the terminal current is 5 A (rms)?

- A 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_forwardDetermine the conductor sizes for a feeder to a panelboard.
