R3 a) Using mesh analysis (format approach) find the matrix R and E of the equation RX I = E. b) Find the unknown currents I1, 12, 13, IRI, IRS of the network in mA using mesh analysis. c) Indicate on the circuit IRI, IRS current directions. Note: The format of the matrixes is only whole numbers; the answers format is three digits after decimal point (for example, 32.223) www 4 www IR R4 IRS R₁ E₁ R = E = I₁ => 12- 13- IRI = IRS- 4 E1=3; E2=15; R1=25; R2=8; R3=40; R4=26; R5=22;
