This is the 3rd time i'm asking this. SOLVE THIS AND FIND V0 , the last answer i was given is -2V which is not even one of the listed options. the listed options are: 12V,4V,24V,6V. first answer given to me was 4V but after i simulated on ltspice albeit i'm not sure if i simulated correct i got a different answer and when i solved it myself i got a different answer. this is my last remaining question. PLEASE SOLVE CORRECTLY AND PROPERLY. NODAL ANALYSIS IS BEST TO USE HERE. IT IS AN IDEAL OP-AMP. SIMULATE USING LTSPICE AND GIVE ME FINAL ANSWER IF POSSIBLE AS THAT IS ALL I CARE ABOUT NOT THE PROCESS. THANK YOU. WILL UPVOTE CORRECT ANSWER, but downvote wrong answer.
Find the exact value of V0. This question was already asked here and the answer was 4V i solved it myself and got a different answer and when i simulated it i also got a different answer.But i might be wrong. so please solve this for me and IF POSSIBLE simulate it so we can be 100% sure that the answer is correct as it's very important that i understand where i went wrong.

- 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. It is a 120/240-volt,single-phase system. The OCPD has a rating of 100 amperes. The calculated load is15,600 VA. All the loads are 120 volts.arrow_forwardCalculate the neutral current in a 120/240-volt, single-phase system when the current inphase A is 20 amperes and the current in phase B is 40 amperes. The load is resistive. Calculate the neutral current in a 208Y/120-volt, 3-phase, 4-wire system when thecurrent in phase A is 0, in phase B is 40, and in phase C is 60 amperes.
