Fahmidda Awoodda Matoorka Kulaylka
Awoodda matoorka kulaylka waa heerka tamarta kulaylka loogu beddelo tamar farsamo. Awoodda waxaa lagu cabbiraa watts (W), halkaas oo 1 watt ay la mid tahay 1 joule ilbiriqsikiiba. Matoorada kulaylka waxay ku shaqeeyaan mabaadi'da thermodynamics, gaar ahaan wareegga thermodynamic, kaas oo ku lug leh is-weydaarsiga kulaylka iyo shaqada.
Qaacidada aasaasiga ah ee awoodda (\( P \)) ee matoorka kulaylka waa:
\[ P = \frac{W}{t} \]

\[ P = \eta_{\text{Carnot}} \times \frac{Q_H}{t} \]
\[ P = 0.5 \times \frac{5000 \, \text{J}}{1 \, \text{s}} \]
\[ P = 0.5 \ jeer 5000 \]
