Need this done asap with 100% accurate solution please. Thanks.

3. Four resistors Ri=4.00 2, R2=13.0 2, R3=10.0 2, and R455.00 2 are mounted as shown in the figure. The voltage of the battery is V = 14 Volts. What is the current in the R1 resistor? Amps -www- R -www- R3 RA

Answer 1

23. R3 B R, = 42 ; R₂ = 132 : R3 = 102 ; R4 = 5.2; V=148 Resistor R, and R₂ is in parallel. Let Rs be the equivalent resistance between R, and R₂ ks : kant B - 17 13 +4 52 4 13 52 » Rs = 7 Now Rz and Rs are also in parallel because both resistors are connected between same terminals. Let Ro be its equivalent resistance da det kan * 5 + to = 20 => R6 = 10 Now the circuit becomes LI

let us say potential at A ,VA=0 then VB = v= 14V current, I, in the circuit will be a I V - 14 - 14X3452 51+ 520 Rst R6 | دن I = 3.824 A let Ve be the potential at c. Also, I = V(-VA 1 R6 3.824 =3Vc = V = 3.824 x 10 10 3 Ve=12.750 Now, UR ARE 10 I 4 Rz current in R = 4 (say) 4 = VB - VC - 14 -12.75 = 0.3125 ER 4 4 = 0.3125 A 420.31 A in
