Answer 1

So 2A will be now divided in R, &Razus Net Rus 5 Rus & R3 in series parallel so R34 Ry & Rs in series so Rut R5 = 1575 = 20 12 R2 w Rus= Ry Rs 30 IS 66 Rus (tiga) - 12 2 R2 R3u5 + R3 Rus R3t Rus R3 Rus RB45 - R3 xRus 30x 26 R₂ + Rus 50 Now R345 & R2 in series So R2345 = R2fRgus =8+12= 202 R2345 & Rl in parallel so ut R R. RIXR2345 Ri R3 Rus fig2) R2 RitR2345 60x20 80 B2. MRI R345 Iv- 30 Sled = 2A (figs) R2345 Using voltage division in Iulitreesus. I RIF 2 x R2345 RitR2345 figy) 2 x 20 60+20 2x20 80 -0.5 A 24 Repp:15 2017 . I R2345 Iv- Iria o 2-0.5 115 A - ffigs)

Now on figure (3) Ra & Raus in series so ssame ceerrent IR2 = 1.5A & I Rzus Now in figure (4) using voltage division rule: 1 345 X Rus. I lis x 20 1.5 x 20 R3 +Ru5 = 0.6A 30 + 20 so Naw I R45 = I2345 - IR 3 = 105.0.6 - 0.9A Since Ra & Ros in series so both will carry Curnent że IRS = 0.9A the same IRU Resistor Current (A) voltage (V) IR VE < 60 0.5 30 8 30 0.6 18 4.5 13-5 0.9
