Circuito Paralelo y división de corriente
-
-
dos elementos están en paralelo si están conectados entre el mismo par de notas. Si cada elemento está en paralelo con todos los demás elementos, se denomina circuito paralelo.
-
la resistencia equivalente de la resistencia conectada en paralelo es
la conductancia equivalente es la suma de la conductancia individual
