Jawaban:
1.
I = 3 A
t = 1 menit = 60 s
W = 9 J
a. Q = ?
I = Q/t
Q = It = 3 x 60 = 180 C
b. V = ?
W = QV
V = W/Q = 9/180 = 0,05 volt
2.
L = 50 m
ρ = 10⁻⁷ ohm m
R = 2,2 ohm
A = ?
ρ = R A/L
A = ρL/R = 10⁻⁷ x 50 / 2,2 = 22,7x10⁻⁷ m²
3.
a. R = 3+2+4 = 9
b. 1/R = 1/6+1/2 = 1/6 + 3/6 = 4/6
R = 6/4 = 1,5
c. Rs = 2+3 = 5
1/R = 1/Rs + 1/10 = 1/5+1/10 = 2/10+1/10 = 3/10
R = 10/3 = 3,33
d. 1/Rp = 1/1+1/2 = 2/2+1/2 = 3/2
Rp = 2/3
R = Rp + 3 = 2/3 + 3 = 3,67
