Question

Device which transform one form of energy in to another form of energy is called a (A) Transducer (B) Transformer (C) Transponder (D) Transistor

Short answer

The correct answer is (A) Transducer, as it is a device that converts one form of energy to another form of energy.

Step-by-step solution

Understanding the Options

First, let's briefly understand what each of the given options is: (A) Transducer - A device that converts one form of energy to another (B) Transformer - A device that transfers electrical energy from one circuit to another through electromagnetic induction (C) Transponder - An electronic device that receives and retransmits a signal (D) Transistor - A semiconductor device that amplifies or switches electronic signals and electrical power

Comparing the Options to the Requirement

Now, let's compare the given options to the requirement, which is specifically a device that transforms one form of energy into another form of energy. (A) Transducer - This clearly matches our requirement, as it converts one type of energy to another. (B) Transformer - While it transfers electrical energy between circuits, it does not change the type of energy. (C) Transponder - Receiving and retransmitting a signal does not involve transforming energy types. (D) Transistor - Although it amplifies or switches signals and power, it does not convert energy types.

Concluding the Answer

Based on the comparison, we can conclude that the correct option is: (A) Transducer - A device that converts one form of energy to another form of energy.
