you need to take 3 of those resistors and do a delta to wye transformation. I'll transform the 25,15, and 10

R1 = 25•15 / (25+15+10) = 375/50 = 7.5

R2 = 150/50 = 3

R3 = 250/50 = 5

now you have 25 series 5 = 30

10 series 7.5 = 17.5

those two in parallel = 30•17.5/47.5 = 11.1 Ω

that is in series with 4 and 2.5 = 17.6

and I = E/R = 15/17.5 = 0.85 amps
