hi ive been asked to complete nodal and mesh analysis on the above circiut in order to find the voltage across R6. i have managed to complete the mesh analysis and also i have used SPICE so i know i am looking for 4v across R6 im at a complete loss now however with nodal. i think i have formulea correct for N1. N2 & N3 however i am stuck at this point N1= (1/ 2k)N1 - (1/1k8)N2 = 1v/2k = 5mA N2 = -(1/2k)N1 + (1/2k + 1/8k)N2 + (1/4k8)N3 = 16/2k = 2mA N3 = 0*N1 + (-1)N2 +(1)N3 = 14.4/4k8 = 3mA i think the above is correct however i am well & truly stuck now. any help would be much appriciated.
