cari Impedansi (Z)
Lalu cari I
jawaban A
Nomor 32
I = 5 Ampere
B = 0,2 Tesla
L = 1 meter
F = ? dan arahnya ?
F = BIL
F = 0,2 * 5 * 1 = 1 Newton
Arahnya gunakan aturan tangan kanan terbuka
Telapak tangan ==> Gaya Lorentz (F)
Keempat jari ==> Medan magnet (B)
Jempol ==> Arus Listrik (I)
Medan magnet (B = Keempat Jari) ke (-)Y
Arus Listrik (I = Jempol) ke (-)X
Gaya Lorentz (F = Telapak Tangan) ke (+)Z
Jawaban A
R=60
XL=100
XC=20
I?
Z=AKAR R KUADRAT+ (XL-XC)KUADRAT
Z=/3600+6400
Z=/10000
Z=100
SHG I=V:Z
I=200:100=2 A
