matlab - Simulink Simscape simple circuit not working -

-

i new matlab , i'm trying make simple circuit in simulink library simscape. have ac voltage source rms value 50v , frequency 50hz. shown in image, scope displays noise, not sine wave expected.

what problem? thanks.

enter image description here

no, scope display correct signal, sine wave @ 50hz. 50hz corresponds period of 20ms, if want see sine wave correctly, need zoom in until have sufficient resolution, e.g. between 1s , 1.06s give 3 periods worth. right now, looking @ whole signal 0 10s, why appears "noise".

if when zooming, find plot not appear "smooth" enough, need adjust solver settings (you don't are) take smaller time steps.
