Answer:
A
Explanation:
What you write in your journals should be related to the topic. and it would be useful to look back on.
Answer:
Energy= 46.08KJ
Explanation:
Given that the power needed to light each bulb is 32W
We know that Power =
The energy needed to light one bulb=
Given time = 1minute = 60 seconds
Energy = =1920J
Therefore energy needed to light one bulb is 1920J
The energy needed to light 24 bulbs = =46080J=46.08KJ
Multiply the numerator and denominator of the first fraction by 3. Multiply the numerator and denominator of the second fraction by 4. Subtract. 9 twelfths minus 4 twelfths equals 5 twelfths.
Thermoelectric generator is the method by which an electrical potential developed in generators and thermocouple.
<u>Explanation</u>:
- A thermoelectric generator (TEG), is otherwise known as a Seebeck generator, it is a solid-state device that directly converts heat flux into electrical power by a phenomenon called a Seebeck effect.
- Thermoelectric generators operate like heat engines except they are less voluminous and have no movable parts. TEGs are therefore usually more costly and competitive and it's efficient is less.
- Thermoelectric generators may be used in power plants to transform excess heat into extra electrical power, and in machines to improve fuel efficiency.
