Limits of expressions involving the trigonometric functions can be evaluated by direct substitution --- unless division by zero is encountered. When division by zero is encountered, simplifications such as the ones presented in the Conceptual Understanding of Limits lesson can be attempted.
A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an excessive electric current limited only by the Thevenin thÃ©venin equivalent resistance of the rest of the network and potentially causes circuit, damage, overheating fire or. explosion
Stranded Power. Stranded Power is electricity that is wasted or unable to be used, normally because where its source is located. The facilities or ability to get it to market may not be available, such as the necessary electric grid is not adequate or in existence. In the wind belt, we have significant amounts of stranded power, particularly at night when the wind blows and the turbines create unneeded electricity.
