   Kirchhoff's rules are rules that allow you to determine the current in any part of a branched circuit by the resistances given in those parts and the EYUs applied. Represents the relationship between alternating current or quasi-stationary current (slow alternating current) and voltage in a branched electrical circuit of conductors. In 1847 it was discovered by G.R. Kirchhoff.
   
4. 
   According to Kirchhoff's second law, the product of the currents of 1K in the corresponding parts of the chain in any arbitrarily selected closed loop of a conductor in a branched electric circuit is equal to the sum of the resistances R of these parts in the circuit, ie X / tRk = X ek, where ya-
   
5. 
   Any linear electrical network containing only voltage sources, current sources and resistances can be replaced at terminals A-B by an equivalent combination of a voltage source Vth in a series connection with a resistance Rth.
   

Conclusion

I did this lab work and learned the laws of Kirchhoff and the laws of thevenin. I learned how to connect resistors in parallel. I put my work in a table.
