Answer 1

Jawaban:

1.

I = Q/t

Q = I t  

t = 5 menit =300 detik

Q = 15*300 = 4500 C

2.

I = V/R = 12/3 = 4 A

3.

I1 = I2 + I3 + I4  

18 = 4 + I3 + 6

I3 = 18 -10 = 8 A

4.

R 24 dan R 8 diparalel, selesaikan dulu

1/Rp = 1/24 + 1/8 = 1/24 + 3/24 = 4/24

Rp = 24/4 = 6 ohm

Rp dan R 12 diseri

Rtotal = 6 + 12 = 18 ohm

5.

Cari Rtotal dulu

R 8 dan R 8 diparalel

1/Rp = 1/8 + 1/8 = 2/8

Rp = 8/2 = 4 ohm

Rp dan R 10 diseri

Rtotal = 4 + 10 = 14 ohm

E = V + Vr

E = IR + Ir        r hambatan dlm batre  

30 = I*14 + I*1    R dari Rtotal

30 = 15 I

I = 30/15 = 2 A
