1.Tegangan, arus, dan resistansi
(Hukum Ohm)
V = IR
Ket :
V=Tegangan
I= Arus
R=Resistansi (Tahanan,Hambatan)
2.Resistansi dan resistivitas

Ket:
R=Resistansi(Ω),
ρ =Resistivitas(m Ω)
A=Luas penampang (m^2)
3.Muatan, arus, waktu Q = It Ket:
Q=Muatan,
I= arus,
t= waktu
4. Daya, arus, tegangan
P = IV
Ket:
P=Daya,
I=arus,
V=Tegangan
5. Daya, Tegangan, dan Resistansi

6.Daya arus resistansi

7. Reluktansi, dan Permeabilitas

. Fluks, dan kerapatan Fluks
B= Φ/A
Ket:
B=Kerapatan Fluks,
Φ= Fluks total (Weber),
A= Luas medan magnet(m^2)
9. Arus, dan intensitas medan magnetik

Ket:
H = gaya pemagnetan,
N= Jumlah lilitan,
I= arus,
