A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. This type of reaction involves the transfer of electrons from one material to another via an electric circuit.
What converts chemical energy into electricity?
The correct answer is Battery. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
Can you convert chemical energy to electrical?
You use a galvanic cell to convert chemical energy into electrical energy. As the chemical reactions occur in the internal circuit, electrons carry electrical energy through a wire in the external circuit. … Thus, a galvanic cell converts chemical energy into electrical energy.
Which device converts sound energy to electrical energy?
A microphone is a transducer that converts sound energy (varying air pressure) into electrical energy.
Is the voltaic cell a device for changing chemical energy to electrical energy or vice versa explain?
A galvanic (voltaic) cell converts the energy released by a spontaneous chemical reaction to electrical energy. An electrolytic cell consumes electrical energy from an external source to drive a nonspontaneous chemical reaction.
What device converts sound to electricity?
electromechanical transducer, any type of device that either converts an electrical signal into sound waves (as in a loudspeaker) or converts a sound wave into an electrical signal (as in the microphone).
What device converts sound waves to electric current?
A microphone converts sound into a small electrical current. Sound waves hit a diaphragm that vibrates, moving a magnet near a coil. In some designs, the coil moves within a magnet. Other microphones, such as condenser microphones, work on the principle of capacitance.
What device transmits and receives electrical signal?
The antenna picks up the radio waves and converts it into a tiny electrical voltage which is passed onto the coil and capacitor. These two devices form what is known as a tuned circuit that filters out most of the radio signals and just lets one through.
