1. Tha ceithir comasairean , C1 = 2 μF, C2 = 1 μF, C3 = 3 μF, C4 = 4 μF, ceangailte ann an co-shìnte. Obraich a-mach comas aon chomasair a bhios leis an aon bhuaidh ris a’ chothlamadh.
Aithnichte:
Comharaiche C1 = 2 μF
Comharaiche C2 = 1 μF
Comharaiche C3 = 3 μF
Comharaiche C3 = 4 μF
A dhìth: An comas co-ionann
fuasgladh:
An comas co-ionann:
C = C1 + C2 + C3
C = 4 μF + 2 μF + 3 μF = 9 μF
Is e 9 μF an comas co-ionann den cho-mheasgachadh gu lèir.

2. Obraich a- mach an cosgais air comasair C2 ma tha an diofar comasach eadar puingean A agus B 9 Volts…
Aithnichte:
Meud C 1 = 20 μ F = 20 x 10 -6 F
Meud C 2 = 30 μ F = 30 x 10 -6 F
Eadar-dhealachadh comasach eadar puingean A agus B (V AB ) = 9 Volts
A dhìth : an cosgais air comasair C₂ ( Q₂ )
fuasgladh:
Eadar-dhealachadh comasach:
Tha comasairean ceangailte ann an co-shìnte gus am bi an diofar comasach eadar A agus B (V AB ) = an diofar comasach air comas C 1 (V 1 ) = an diofar comasach air comas C 2 (V 2 ) = 9 Volts.
Cosgais dealain air comasair C2 :
Q² = C² V² = (30 x 10⁻⁶ ) ( 9) = 270 x 10⁻⁶ C
Q2 = 270 μC
Tha an cosgais dealain air comasair C₂ 270 μC.

3. Tha trì comasairean, C1 = 4 μF, C2 = 2 μF, C3 = 3 μF, ceangailte ann an co-shìnte. Tha na comasairean air an cur fo chasaid. Tha an diofar comasach air comas C2 4 Volts. Obraich a-mach
(a) Cosgais dealain air comasairean C1 , C2 agus C3
(b) Cosgais dealain air comasair co-ionann an cothlamadh gu lèir
Aithnichte:
Meud C 1 = 4 μ F = 4 x 10 -6 F
Comharradair C2 = 2 μF = 2 x 10-6 F
Comharradair C3 = 3 μF = 3 x 10-6 F
Eadar - dhealachadh comasach air comasair C₂ (V₂ ) = 4 Volts
A dhìth : Cosgais dealain air comasair C3 ( Q3 )
fuasgladh:
(a) Cosgais dealain air comasair C3
An diofar comasach air comasair C3 :
Tha comasairean ceangailte ann an co-shìnte gus am bi an diofar comasach air a’ chomasair C3 (V3) = an diofar comasach air capacitor C2 (V2) = an diofar comasach air capacitor C1 (V1) = an diofar comasach air comasair co-ionann (V) = 4 Volt
Cosgais dealain air comasair C1 :
Q1 = C1 V1 = (4 x 10-6 ) (4) = 16 x 10-6 C
Q1 = 16 μC
Cosgais dealain air comasair C2 :
Q2 = C2 V2 = (2 x 10-6 ) (4) = 8 x 10-6 C
Q2 = 8 μC
Cosgais dealain air comasair C3 :
Q3 = C3 V3 = (3 x 10-6 ) (4) = 12 x 10-6 C
Q3 = 12 μC
(b) Cosgais dealain air comasair co-ionann
Q = Q1 + Q2 + Q3
Q = 16 μ C + 8 μ C + 12 μ C = 36 μ C
Fuasgladh eile:
An comas co-ionann:
C = C1 + C2 + C3
C = 4 μF + 2 μF + 3 μF = 9 μF
C = 9 x 10⁻⁶ F
An diofar comasach air a’ chomasair co-ionann:
V 1 = V 2 = V 3 = V = 4 Volt
An cosgais dealain air a’ chomasair co-ionann:
Q = CV = (9 x 10⁻⁶ ) (4) = 36 x 10⁻⁶ C
Q = 36 μC
