Question

In a temporary forest camp, the best way to generate electricity for several hours is to use the following engine.
A. Steam engine
B. Petrol engine
C. Hand operated dynamo
D Diesel engine

Answer 1

Hint: There are various ways to generate electricity. Depending on the power of the machine or device we have to use it. Here, turbines are used for the large scale. The turbine is used to generate electricity on a large scale with the help of steam and water. For a small scale, we use engines to produce electricity with the use of steam and fuel.

Complete step by step answer:
We know that the steam engines are used to generate electricity for several hours in a temporary forest camp. Steam engines are the kind of engines that are used to generate electricity by means of steam. Also, it is a kind of heat engine that transforms the water into steam. Moreover, the expansion principle used in the heat engine to convert it into steam and then produce it into electricity.
We know that, in the forest, there is lots of wood to produce fire. Now, this fire produces steam, so this steam can be utilized in a steam engine and performs mechanical work to produce electricity.
So, in this way in the forest camp, the best way to generate electricity for several hours is a Steam engine.

So, the correct answer is “Option A”.

Note:
In this question, students are confused between the engines and the generator. We have to know that the engine is the mechanical member used to produce motion with the help of input power. In contrast, the generator is the device that produces electricity with the help of mechanical input.
