Ihe atụ nke Ajụjụ Mkparịta ụka nke Usoro Circuit
Ajụjụ Ihe atụ nke 1: Ịgbakọ mkpokọta ọkụ eletrik na sekit usoro
Ajụjụ: Sekit usoro nwere resistors atọ nwere resistors \( R_1 = 2 \Omega \), \( R_2 = 3 \Omega \), na \( R_3 = 5 \Omega \). Ọ bụrụ na voltaji isi mmalite bụ 10 V, ole ka ọkụ eletrik na-asọfe na sekit ahụ?
Azịza:
Nzọụkwụ 1: Gbakọọ nguzogide zuru oke nke sekit usoro ahụ.
\[ R_{mkpokọta} = R_1 + R_2 + R_3 \]
\[ R_{total} = 2 \Omega + 3 \Omega + 5 \Omega \]
\[ R_{mkpokọta} = 10 \Omega \]
Nzọụkwụ nke 2: Jiri Iwu Ohm gbakọọ mkpokọta ọkụ eletrik.
\[ I = \frac{V}{R_{mkpokọta}} \]
\[ I = \frac{10 V}{10 \Omega} \]
\[ I = 1 A \]
Ya mere, ugbu a na-asọfe na sekit ahụ bụ 1 Ampere.
Ajụjụ Ihe Nlereanya nke 2: Ịgbakọ Mbelata Voltaji n'ofe Resistor
Ajụjụ: N'otu sekit ahụ dịka ọ dị na ajụjụ nke mbụ, kedu ka mbelata voltaji si agafe resistor ọ bụla?
Azịza:
Nzọụkwụ 1: Anyị amatala mkpokọta ọkụ eletrik dị na sekit ahụ, nke bụ 1 A.
Nzọụkwụ nke 2: Jiri Iwu Ohm gbakọọ mbelata voltaji n'ofe resistor ọ bụla.
– Mbelata voltaji gafere \( \\R_1 \):
\[ V_1 = I \ugboro R_1 \]
\[ V_1 = 1 A \ugboro 2 \Omega \]
\[ V_1 = 2 V \]
– Mbelata voltaji gafere \( \\R_2 \):
\[ V_2 = I \ugboro R_2 \]
\[ V_2 = 1 A \ugboro 3 \Omega \]
\[ V_2 = 3 V \]
– Mbelata voltaji gafere \( \\R_3 \):
\[ V_3 = I \ugboro R_3 \]
\[ V_3 = 1 A \ugboro 5 \Omega \]
\[ V_3 = 5 V \]
Nzọụkwụ nke 3: Hụ na ọnụego mbelata voltaji ahụ kwekọrọ na voltaji isi mmalite.
\[ V_{ngụkọta} = V_1 + V_2 + V_3 \]
\[ V_{ngụkọta} = 2 V + 3 V + 5 V \]
\[ V_{ngụkọta} = 10 V \]
Ya mere, mbelata voltaji n'ofe resistor ọ bụla bụ \(V_1 = 2 V \), \(V_2 = 3 V \), na \(V_3 = 5 V \).
Ajụjụ Ihe Nlereanya nke 3: Ịchọpụta Nguzogide nke Resistor na Circuit
Ajụjụ: Usoro sekit nwere resistors abụọ \( R_1 = 4 \Omega \) na \( R_2 = 6 \Omega \). A chọrọ itinye resistors nke atọ na sekit ahụ ka nguzogide zuru oke wee bụrụ 15 \(\Omega \). Gịnị bụ uru resistors nke atọ?
Azịza:
Nzọụkwụ 1: Gbakọọ nguzogide achọrọ iji nweta 15 \(\Omega\).
\[ R_{mkpokọta} = R_1 + R_2 + R_{3} \]
\[ R_{3} = R_{mkpokọta} – (R_1 + R_2) \]
\[ R_{3} = 15 \Omega – (4 \Omega + 6 \Omega) \]
\[ R_{3} = 15 \Omega – 10 \Omega \]
\[ R_{3} = 5 \Omega \]
Ya mere, uru nke atọ nke resistor nke a chọrọ itinye bụ 5 \(\Omega\).
Ihe atụ Ajụjụ nke 4: Ịgbakọ Ike E Ji Eme Ihe n'usoro Sekit
Ajụjụ: N'ajụjụ nke mbụ, ike ole ka sekit ahụ dum na-eri?
Azịza:
Nzọụkwụ nke 1: Jiri usoro ike eletrik \( P = V \times I \).
\[ P_{ngụkọta} = V_{ngụkọta} \ugboro I \]
\[ P_{ngụkọta} = 10 V \ugboro 1 A \]
\[ P_{ngụkọta} = 10 W \]
Ya mere, ike nke sekit dum na-eri bụ 10 Watts.
Nzọụkwụ nke 2: Chọpụta ike nke resistor ọ bụla na-eri.
– Ike na \(R_1\):
\[ P_1 = V_1 \ugboro I \]
\[ P_1 = 2 V \ugboro 1 A \]
\[ P_1 = 2 W \]
– Ike na \(R_2\):
\[ P_2 = V_2 \ugboro I \]
\[ P_2 = 3 V \ugboro 1 A \]
\[ P_2 = 3 W \]
– Ike na \(R_3\):
\[ P_3 = V_3 \ugboro I \]
\[ P_3 = 5 V \ugboro 1 A \]
\[ P_3 = 5 W \]
Oke ike e ji eme ihe:
\[ P_{mkpokọta} = P_1 + P_2 + P_3 \]
\[ P_{ngụkọta} = 2 W + 3 W + 5 W \]
\[ P_{ngụkọta} = 10 W \]
