| Ohm’s Law modified for AC circuits with sinusoidal signals | U’=ZxI’, where U’ & I’ -voltage and current phasors, Z-complex impedance (u=Rxi) | Lorentz force law, Faraday’s law and Drude model |
| Kirchhoff’s Current Law (KCL) | The sum of electrical currents which flow into any junction in an electric circuits is equal to the sum of currents which flow out | Conservation of electric charge |
| Kirchhoff’s Voltage Law (KVL) | The sum of electrical voltages around a closed circuit must be zero | Conservation of energy |
