Ihe atụ nke ajụjụ mkparịta ụka gbasara sekit Capacitor
Kapasitọ bụ ihe eletrọniki nke na-echekwa ike eletriki n'ụdị ubi eletriki. N'ọtụtụ ngwa eletrọniki na sekit eletriki, a na-ejikarị kapasitọ eme ihe maka nzacha, nchekwa, ma ọ bụ nhazi akara. N'isiokwu a, anyị ga-atụle ọtụtụ ihe atụ ma tụlee sekit kapasitọ, ọkachasị ndị a haziri n'usoro na ndị yiri ya.
Isi ihe gbasara ike
Tupu anyị abanye n'ajụjụ mkparịta ụka, ọ dị mma ịghọta ụfọdụ echiche bụ isi gbasara capacitors:
1. Ike (C): Ike (Capacitance) bụ ihe a na-eji atụ ikike capacitor nwere ịchekwa chaja kwa voltaji, ya na nkeji nke Farads (F). N'ọrụ, a na-ejikarị obere nkeji dịka microfarads (μF), nanofarads (nF), ma ọ bụ picofarads (pF).
2. Ike echekwara: A na-agbakọ ike echekwara na kapasitọ site na iji usoro:
\[
E = \frac{1}{2} CV^2
\]
ebe \(E \) bụ ike dị na joules, \(C \) bụ capacitance dị na farads, na \(V \) bụ voltaji dị na volts.
3. Sekit Usoro Capacitor: Sekit ndị ejikọtara na usoro nwere mkpokọta ikike \( C_{\text{total}} \) nke enwere ike ịgbakọ site na iji usoro:
\[
\frac{1}{C_{\text{total}}} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3} + \ldot
\]
ebe \(C_1, C_2, C_3, \ldots \) bụ ikike nke capacitor ọ bụla.
4. Sekit Capacitor Parallel: Capacitors ejikọtara na parallel nwere mkpokọta capacitance \( C_{\text{total}} \) nke enwere ike ịgbakọ site na iji usoro:
\[
C_{\text{total}} = C_1 + C_2 + C_3 + \ldot
\]
Ihe atụ nke 1: Sekit Usoro Capacitor
Soal
A na-ejikọ capacitors abụọ nwere capacitances \(C_1 = 5 \mu F \) na \(C_2 = 10 \mu F \) n'usoro. Gbakọọ ike niile nke sekit ahụ.
Mkparịta ụka
Site na iji usoro capacitance usoro:
\[
\frac{1}{C_{\text{total}}} = \frac{1}{C_1} + \frac{1}{C_2}
\]
Mgbe ahụ, nnọchi nke ụkpụrụ:
\[
\frac{1}{C_{\text{total}}} = \frac{1}{5 \mu F} + \frac{1}{10 \mu F}
\]
\[
\frac{1}{C_{\text{total}}} = \frac{2}{10 \mu F} + \frac{1}{10 \mu F}
\]
\[
\frac{1}{C_{\text{total}}} = \frac{3}{10 \mu F}
\]
N'ihi ya, ikike niile dị na ya:
\[
C_{\text{total}} = \frac{10 \mu F}{3} = 3.33 \mu F
\]
Ya mere, mkpokọta ikike nke sekit usoro nke capacitors abụọ ahụ bụ \( 3.33 \mu F \).
Ihe atụ nke abụọ: Sekit Capacitor Parallel
Soal
A na-ejikọ capacitors abụọ nwere capacitances \( C_1 = 4 \mu F \) na \( C_2 = 6 \mu F \) n'otu oge. Gbakọọ ike niile nke sekit ahụ.
Mkparịta ụka
Site na iji usoro ikike nha anya:
\[
C_{\text{mkpokọta}} = C_1 + C_2
\]
Mgbe ahụ, nnọchi nke ụkpụrụ:
\[
C_{\text{total}} = 4 \mu F + 6 \mu F
\]
\[
C_{\text{total}} = 10 \mu F
\]
Ya mere, mkpokọta ikike nke sekit parallel nke capacitors abụọ ahụ bụ \( 10 \mu F \).
Ihe atụ nke atọ: Ike echekwara n'ime Capacitor
Soal
A na-eji ike nke \( 12 V \) chajị capacitor nwere ike nke \( 2 \mu F \). Gbakọọ ike echekwara na capacitor ahụ.
Mkparịta ụka
A na-agbakọ ike echekwara na capacitor site na iji usoro a:
\[
E = \frac{1}{2} CV^2
\]
Mgbe ahụ, nnọchi nke ụkpụrụ:
\[
E = \frac{1}{2} \cdot 2 \mu F \cdot (12 V)^2
\]
\[
E = \frac{1}{2} \cdot 2 \mu F \cdot 144 V^2
\]
\[
E = 1 \mu F \cdot 144 V^2
\]
\[
E = 144 \mu J
\]
Ya mere, ike echekwara na capacitor bụ \( 144 \mu J \).
Ajụjụ Ihe Nlereanya nke 4: Nchikota Usoro na Nchikota Ndị Na-esochi Ya
Soal
A na-ejikọ capacitors atọ \(C_1 = 2 \mu F \), \(C_2 = 3 \mu F \), na \(C_3 = 6 \mu F \) na njikọ usoro na parallel dịka egosiri na eserese dị n'okpuru. A na-ejikọ capacitors \(C_1 \) na \(C_2 \) n'usoro, wee jikọọ ha na capacitor \(C_3 \). Gbakọọ ikike zuru oke nke sekit ahụ.

Nke mbụ, gbakọọ mkpokọta ikike nke \(C_1 \) na \(C_2 \) ejikọtara na usoro:
\[
\frac{1}{C_{12}} = \frac{1}{C_1} + \frac{1}{C_2}
\]
\[
\frac{1}{C_{12}} = \frac{1}{2 \mu F} + \frac{1}{3 \mu F}
\]
\[
\frac{1}{C_{12}} = \frac{3}{6 \mu F} + \frac{2}{6 \mu F}
\]
\[
\frac{1}{C_{12}} = \frac{5}{6 \mu F}
\]
N'ihi ya, ikike capacitance ahụ dị ka ndị a:
\[
C_{12} = \frac{6 \mu F}{5} = 1.2 \mu F
\]
Na-esote, \(C_{12} \) ejikọtara n'otu oge na \(C_3 \), wee:
\[
C_{\text{mkpokọta}} = C_{12} + C_3
\]
\[
C_{\text{total}} = 1.2 \mu F + 6 \mu F
\]
\[
C_{\text{total}} = 7.2 \mu F
\]
Ya mere, mkpokọta ikike nke sekit njikọta bụ \( 7.2 \mu F \).
