LISTRIK DINAMIS
• Kuat Arus
Persamaan untuk soal 1 — 3
i = Q / t
1][
t = ½ menit = 30 s
Q = 150 C
i = __?
kuat arus
i = Q / t
i = (150 C) / (30 s)
i = 5 A ✓
2][
i = 2 A
t = 1 menit = 60 s
Q = __?
muatan listrik
i = Q / t
Q = i t
Q = (2 A) (60 s)
Q = 120 C ✓
3][
i = ½ A
Q = 1800 C
t = ___?
waktu
i = Q / t
t = Q / i
t = (1800 C) / (½ A)
t = 3600 s = 1 jam ✓
Persamaan untuk soal 4 — 5
W = Q ∆V
4][
W = 210 J
Q = 30 C
∆V = __?
beda potensial
W = Q ∆V
∆V = W / Q
∆V = (210 J) / (30 C)
∆V = 7 V ✓
5][
∆V = 24 V
Q = 15 C
W = __?
energi
W = Q ∆V
W = (15 C) (24 V)
W = 360 J ✓
