1. Tha trì comasairean, C1 = 2 μF, C2 = 4 μF, C3 = 4 μF, ceangailte ann an sreath agus co-shìnte . Obraich a-mach comas aon chomasair a bhios leis an aon bhuaidh ris a’ chothlamadh.
Aithnichte:
Comharaiche C1 = 2 μF
Comharaiche C2 = 4 μF
Comharaiche C3 = 4 μF
A dhìth: An comas co-ionann (C)
fuasgladh:
Tha comasairean C2 agus C3 ceangailte ann an co-shìnte. An comas co-ionann :
C P = C 2 + C 3 = 4 + 4 = 8 μ F
Tha comasairean C1 agus Cp ceangailte ann an sreath. An comas co-ionann :
1/C = 1/C 1 + 1/ C P = 1/2 + 1/8 = 4/8 + 1/8 = 5/8
C = 8/5 μF
