Tambaya mai Karamin Kirki: Me kana? (Kuma Yadda Ya Tufayi Da Tambaya mai Karamin Kashi)

Na wani Open Circuit?

An open circuit ita ce electric circuit inda karamin karamin ba ta shiga. Karamin karamin zai iya shiga a cikin circuit idan yake da hanyar gaba mai tsawo—wanda ake kira “closed circuit”. Idan akwai kisan karamin a nan a cikin circuit, kana da open circuit, kuma karamin karamin ba zai iya shiga.

A cikin open circuit, farkon terminal bi suka dace. Saboda haka, tsari na circuit ya dace. Amma idan karamin karamin ba zai iya shiga a cikin circuit, akwai voltage drop a kan biyu mafi girman cikin circuit.

Saboda haka a cikin open circuit, karamin karamin da ke shiga a cikin circuit ce zero, kuma voltage ta da (non-zero).

Idan Power ita ce , kuma karamin karamin ita ce zero.

Saboda haka power ita ce zero, kuma babu power da ke tafara a nan a cikin open circuit.

Resistance na open circuit ita ce mafi girma a cikin bayanan.

Resistance na Open Circuit

Kyauwar resistor ita ce Ohm’s law. Voltage across the resistor is proportional to the current. Saboda haka, equation of ohm’s law ita ce,

A cikin open circuit condition, karamin karamin ita ce zero (I = 0).

Saboda haka, don duka yadda voltage, resistance ita ce infinity a cikin open circuit conditions.

Open Circuit vs Short Circuit

A cikin basics na electrical engineering, open circuit da short circuit ita ce biyu mafi girman configurations da kyauwar mafi girman baya.

Duk biyu suna nufin connection na biyu mafi girman cikin circuit. Saboda haka, tambayar ita ce, Me kadan a faruwa a kan open circuit da short circuit?

A cikin open-circuit conditions, karamin karamin da ke shiga a cikin circuit ita ce zero. Amma a cikin short circuit conditions, akwai karamin karamin da ke shiga a cikin circuit da ita ce infinity.

Resistance a kan biyu mafi girman open circuits ita ce infinity. Amma resistance a kan biyu mafi girman short circuits ita ce ideally zero. Amma a cikin practic, akwai resistance da ita ce low.

Voltage a kan biyu mafi girman open circuit ita ce supply voltage. Amma a cikin short circuit, voltage a kan short circuit terminals ita ce zero.

Idan circuit ita ce a cikin normal condition, kuma karamin karamin da ke shiga a kan components, wannan condition ita ce wanda ake kira closed circuit. Karamin karamin zai iya shiga idan an yi close path. A cikin close path, karamin karamin zai shiga daga negative zuwa positive polarity na voltage.

Misali na Open Circuit

A cikin duk misalai, open circuit ita ce saboda breaking a kan conductor. Idan circuit ba ce closed, amma akwai kisan karamin a kan anywhere a cikin loop, karamin karamin ba zai iya shiga. Wannan zai yi open circuit condition.

Idan switch ita ce open, zai iya yi kisan karamin. Yana nufin karamin karamin ba zai iya shiga a cikin wannan condition. Amma wannan ita ce open circuit condition.

Amma idan kana close switch, zai iya yi close path. Amma akwai karamin karamin da za shiga a kan load (bulb). Wannan ita ce normal condition ko closed circuit.

Saboda dukkan conditions, idan akwai kisan karamin a kan positive da negative terminals na battery, karamin karamin zai iya shiga. Amma babu load (resistance). Saboda haka, yana yi short circuit, kuma akwai karamin karamin da ke shiga da ita ce high.
