Electricity and Magnetism

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)$$F=B \cdot I \cdot L$$
Spring Force $$ε=N \cdot \frac{∆Φ}{∆t}$$
