Coulomb's law
|
|
$$|F_1|=|F_2|=k\cdot \frac {|q_1 \cdot q_2|}{r^2}$$
|
|
Electric Field
|
|
$$E=\frac {F}{q}$$
|
|
Magnetic flux
|
|
$$\Phi=B \cdot S$$
|

Ohm’s law
|
|
(1)$$I=\frac{V}{R}$$
(2)$$U=U_1+U_2$$
$$R=R_1+R_2$$
$$I=\frac{U_1}{R_1} =\frac{U_2}{R_2}$$
(3)$$I=I_1+I_2$$
$$\frac{1}{R} =\frac{1}{R_1}+\frac{1}{R_2}$$
$$U=I_1 \cdot R_1=I_2 \cdot R_2$$

Lorentz force
|
|
(1)$$F=q \cdot (E+v×B)$$
(2)$$F=B \cdot I \cdot L$$
