yg gatau gk ush jwb :)

Answer 1

5. V = 220 v , I = 2 A. . R= V/I = 220/2 = 110 ohm

6. Q = 4500 C, t = 15 menit = 900 detik , I = Q/t = 4500/900 = 5 A

7. cari R paralel, 1/R = 1/(2 + 2) + 1/4 = 2/4 --> R = 2 ohm cari I = v / r = 6/2 = 3A

9. R = 800 ohm, I = 250mA = 0,25 A.. V? --> V= I*R = 800 * 0,25 = 200 volt

10. R = 50 ohm, I = 3A , V? --> V= I*R = 50 * 3 = 150 volt

13. R = V/I , yang salah no 4.

15. A = 500 mA = 0,5 A , t = 5 min=  300 s, Q? --> Q = I*t = 300 * 0,5 = 150 C

16, I = 250 mA = 0,25 A , Q = 5000 C, .. t? --> t = Q/I = 5000/0,25 = 20000s

17. V= 15 volt. R = 50 ohm, .. I? --> I= V/R = 15/50 = 0,3 A

20. Hk. KIRCHOFF, I masuk = I keluar. I masuk = I1 , I keluar= I2 + I3, I1 = I2 + I3 => 3 = I2 + 1 ==> I2 = 2 A.

21. Cari R paralel => 1/R = 1/6 + 1/6 => R = 3 Ohm . R total = 6 + 3 = 9ohm

Answer 2

5. R = V/I =220/2 = 110 Ω (a)
6. I = Q/t  (t dalam sekon, t = 15 x 60 =900 s)
    I = 4500/900 = 5 A (d)
7. Rseri = 2+4 = 6 Ω
   Rtotal = 4x6/(4+6) =24/10 =2,4 Ω
   I = V/Rtotal =6/2,4 = 2,5 A (d)
9. V= I.R =0,25 A. 800Ω = 200Volt (b)
10. V=I.R=3.50=150Volt (c)
13. (d) no. 4 seharusnya nilai I = 14,5 mA
15. I = 500 mA = 0,5 A
     t = 5 menit =5 x60 =300 s
     Q = I.t = 0,5 . 300=150 C
16.Q = 5000 C
     I = 250mA = 0,25 A
     t = Q/I = 5000/0,25 =20000s (d)
17. I = V/R = 15/50 =0,3 A (d)
20. I₂ = I₁ - I₃ = 3 - 1 = 2A (a)
21. Rparalel =6x6/(6+6) =36/12 = 3Ω
     Rtotal = 6 + Rparalel =6 + 3 = 9Ω(a)
