Answer:
An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout.
Explanation:
For instance, a simple light switch opens and closes the circuit that connects a light to a power source. When you build a circuit, it's a good idea to disconnect the battery or other power source when the circuit is not in use.

<h2>PAKI BRAINLIEST NALANG PO FOR MY HARD WORK AND MY HARD THINKING</h2>
Answer:
Explanation:
A lifeboat is a boat, specially made to move from land to sea to help people who are in difficulty. Garrett James Hardin, an American environmentalist uses this description of lifeboat to warn of the dangers of human overpopulation which does not only affect the populated nations but everyone. The rich people (mostly the Americans) are the ones in the lifeboats, and the poor ones are in the waters swimming and trying to board any of the lifeboats. The nations who are like lifeboats have a specific-carrying capacity (or limited amount) that should not be exceeded.
If there are fifty people in the lifeboats with ten free spaces that could be given to hundred poor people waiting to be saved, further explanations were offered by Hardin on what to be done. Allowing everyone in, which would mean hundred and fifty people are in the boat at the same time could make it sink. The ten spaces could be offered on who arrives first or the best ten from the hundred poor people could be allowed to come on board. There are some people, among the lucky fifty rich people who would feel guilty according to Hardin, that the remaining ninety could die and so they are willing to give-up their spaces for the less fortunate ones. The best solution would be for no one to be allowed into the boat, preserving the lucky fifty from sinking with the boat as stated by Hardin.
Nations are not actually lifeboats and the human race have grown beyond being measured to have a limited number of persons it can contain as stated by Hardin. The possible maximum number of persons a particular area can contain should never be important to mankind where there is a terrible event affecting human beings. Also the lucky fifty in the lifeboats may think they are safe, but they could be affected by a huge wave in the sea that would make the entire lifeboat nations to drown.
