con carga capacitiva (filtro)
sin carga capacitiva
Circuito
Componentes e instrumentación
1 panel de conexiones
1 diodo 1N4007
3 condensadores : 0.47 uf , 4.7 uf , 100 uf
2 polímetros
1 resistencia de 10k
1 transformador de aislamiento
cables de conexión
osciloscopio
Procedimiento
Realizar el montaje del circuito sin carga capacitiva y ajustar la tensión de entrada a U1 = 20v y anotar el valor de U2
U1 U2
Medida con 20 v ~ 8.5 V-
Voltímetro
Medida con 58 Vpp 28 Vpp
Osciloscopio
Mediciones 56Vpp 28 Vpp
Reales
Realizar el montaje del circuito con carga capacitiva , ajustar la tensión U1 a 20 V , y medir la tensión U2 utilizando el polímetro. Variando el valor de Cl
C1= : 0.47 uf , 4.7 uf , 100 uf , observar , con el osciloscopio el rizado de la tensión U2 para las tres capacidades. Anotar los valores en la tabla.
