Question

find the current through 8 ohm,s resistor using Thevenin,s theorem

Answer 1

Explanation:

.  load impedance has replaced by a short-circuit. ISC = IN = 200/2 = 100A. Norton’s resistance RN can be found by looking into the open terminals of Fig. . For this purpose Δ ABC has been replaced by its equivalent Star. As seen, RN is equal to 8/7 Ω. Hence, Norton’s equivalent circuit consists of a 100 A source having a parallel resistance of 8/7Ω as shown in Fig.. The load current IL can be found by using the Current Divider rule. IL = 100 x (8/7)/(8 + (8/7)) = 12.5A Read more on Sarthaks.com - https://www.sarthaks.com/491057/state-nortons-theorem-find-current-using-nortons-theorem-through-load-the-circuit-shown
