Question

Please explain step by step. please I'm really dumb

Replace everything in the circuit below, except the 4 ohm resistor

Calculate v  

5.18 Calcule v pela substituição de tudo, menos o resistor de 4 A, pelo seu equivalente de Thévenin 852 6 A ISA 252 PROBLEMA 5.18

Answer 1

a 4 4A GA + 1 an 8n 15A ww an To find the venin equivalent circuit we will have to find the venin equivalent voltage and thevenin equivalent resistance. To find the verin equivalent voltage we will remove ur resistance between a b terminal and then find open circuit voltage across ab C 4A In 1²62 + & 6A Vth or b 15A Izlan D all Applying Kirchoff current law at node C and D which states that sum of current entering a node is zero.
