Comharradairean ann an sreath - duilgheadasan agus fuasglaidhean

1. Tha ceithir comasairean, C1 ₌ 2 μF, C2 ₌ 1 μF, C3 ₌ 3 μF, C4 ₌ 4 μF, ceangailte ann an sreath . 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:

1/C = 1/C ₁ + 1/C ₂ + 1/C ₃ + 1/C ₄

1/C = 1/2 + 1/1 + 1/3 + 1/4

1/C = 6/12 + 12/12 + 4/12 + 3/12

1/C = 25/12

C = 12/25

C = 0.48

Is e 0.48 μF an comas co-ionann den cho-mheasgachadh gu lèir.

2. Obraich a-mach an cosgais air comasair C _{1 ma} tha an diofar comasach eadar P agus Q 12 Volt…

Aithnichte:

Comharaiche _C1 = 20 μF = 20 x ^10-6 F​

Comharaiche _C2 = 20 μF = 20 x ^10-6 F​

Eadar-dhealachadh comasach (V) = 12 Volts

A dhìth: an cosgais air comasair _C1 ( _Q1 )

fuasgladh:

An comas co-ionann:

1/C = 1/C1 _{+ 1} / C2

1/C = 1/10 + 1/20 = 2/20 + 1/20 = 3/20

C = 20/3 μ ^F = (20/3) x 10-6 F

Cosgais dealain air a’ chomasair co-ionann:

Q = (C)(V) = (20/3)(12)( ^10-6 ) = 80 x ^10-6 C

Q = 80 μC

Tha comasairean ceangailte ann an sreath gus am bi cosgais dealain air na comasairean co-ionann = cosgais dealain air comasair C1 ₌ cosgais dealain air comasair C2_.

Tha an cosgais dealain air comasair C1 80 μC_.

3. Tha dà _chomh - chomh _...​​​_​​_​​

Aithnichte:

Meud C ₁ = 2 μ F = 2 x ¹⁰ -6 F

Meud C ₂ = 4 μ F = 4 x ¹⁰ -6 F

An diofar comasach air comasair _C1 ( V1 ₎ = 2 Volt

A dhìth : Cosgais dealain air comasair C2_.

fuasgladh:

Cosgais dealain air comasair C1 _:

Q ₁ = C ₁ V ₁ = (2 x 10 ^-6 )(2) = 4 x 10 ^-6 C

Q1 = 4 μC_​

Tha comasairean ceangailte ann an sreath gus am bi cosgais dealain air comasair _C1 = cosgais dealain air comasair C2_.

Tha an cosgais air comasair C2 4 μC_.
