Wani shine Muhimmin Watts?

Muhimmin Watts ya bayyana yadda karshe, amperage, da drop voltage suna iya taimaka a cikin jiki na karshe. Muhimmin Watts ta ce kuma cewa karshe na jiki na karshe shi ne mafi girma daga voltage da current.

Formula na Muhimmin Watts

Formula na Muhimmin Watts zai iya bayar haka. Yana ba da al'amuran da ke tsariwa a karshe (watts), current (amps) da voltage(volt)

$\begin{align*} Power = Voltage\times Current\end{align*}$

$\begin{align*}Voltage = \frac{Power}{Current} \end{align*}$

$\begin{align*}Current = \frac{Power}{Voltage} \end{align*}$

Misalai na Muhimmin Watts 1

Idan kana neman in ka gano yawancin abubuwan 500-watt lighting devices za su iya jagoranci circuit bace ba za su haifar da fuse ba.

Karkashin, kana son in ka gano yadda current ya zama za su iya jagoranci circuit. Karamin darasi suka da 15A circuits da karamin circuits suka da circuit breaker na 20A. Don haka, wani shine total power?

Ana sani cewa Watts = Volts x Amps. Saboda haka, a nan an bayar da values na voltage da current kamar 110V da 20A. Daga baya, an samu Watts 2200W. Saboda haka, wani abu da ake jagoranci circuit ya kamata yake da karshe da 2200 watts, domin haka ne karshe da aka samu a cikin wannan circuit. Zan iya jagoranci four 500-watt lights a cikin circuit (ko two 1000watt lights) da 200 Watt as safety margin.

Misalai na Muhimmin Watts 2

Idan voltage na bulb ya kasance 120 volts da karshe 60 watts, wani shine current?

Saboda haka, a nan an bayar da values na voltage da power kamar 120V da 60W. Ana sani cewa current = Power / Voltage. Saboda haka, a nan an samu value na current 0.5 Amperes.

Misalai na Muhimmin Watts 3

Ka duba bulb da karshe 100 Watt a cikin darasi. Ana sani cewa voltage na bulb ya kasance 110V ko 220V saboda haka, current ya zama za su iya gano haka.

I = P/V = 100W / 110V = 0.91 Amps ko I = P/V = 100W / 220V = 0.45 Amps.

Amma ana iya gano cewa 60W light bulb ya fi kyau. Company na electrical za su biyan in ka yi amfani da Kilo-Watt Hours (kWh). Wani kWh yana nufin cewa energy da ke samun 1000 watts ga waɗanda ke yi 1 hour.

Muhimmin Watts Da Muhimmin Ohm

Muhimmin Watts yana nuna al'amuran da ke tsariwa a karshe, voltage da current.

Karshe: Karshe yana nufin rate da ake amfani da energy. Unit na measurement na electrical power shine Watt, an sake ita kamar James Watt. Idan one Volt ya amfani a jagoranci Ampere through a circuit, work done shine equal to one Watt of power.

$\begin{align*} P = V \times I\end{align*}$

Idan electrons suka jagoranci resistance a cikin jiki na karshe, electrons suka hada da sauransu da atoms da suka take don resistance. Wannan hado suka haifar da heat da kuma loss of energy. Saboda haka, variation na muhimmin watts yana nuna haka

$\begin{align*}P = I^{2}R\end{align*}$
