A semiconductor device that produces electric current through the photo-voltaic effect is a solar cell. When sunlight shines on the cell, it creates an electric current by releasing electrons from the material. This electric current can then be harnessed for various applications, such as generating electricity for homes or powering electronic devices.
Voice Communication is Interexchange of Voice that is Capturing Sound to Electric Signals and Generating Sound from Electric Signals. Voice Communication needs both Input Device (Microphone) and Output Device (Headphones\Speakers). Broadcasting Voice Communication entirely depends on Output Devices at Audience Side.
A battery is a device that produces an electric current by converting chemical energy into electrical energy. This process involves the movement of ions between electrodes within the battery, generating a flow of electrons through a circuit.

The speech generating device was invented by Dr. Robert Weisenberger in the early 1980s. He designed the device to help individuals with communication impairments, such as those with ALS or cerebral palsy, to communicate effectively.
A battery uses chemical energy to convert it into electrical energy, which then provides charges with electric potential energy. The chemical reactions inside the battery create a flow of electrons, generating an electric potential difference that can power various devices.
Electric current powers electronic devices by flowing through the circuits and components within the device, providing the necessary energy for them to function. The current is generated by a power source, such as a battery or outlet, and is controlled and directed by the device's internal circuitry to perform specific tasks, such as powering a screen or generating sound.
The electric motor is the most important device used to convert electricity into motion. It functions by generating a magnetic field that interacts with electrical currents to produce rotational motion. Electric motors are widely used in various applications, from household appliances to industrial machinery, due to their efficiency and versatility.
When an electric current enters a component, it carries energy and can cause the component to perform a function, such as generating light or heat. When the current leaves the component, it has already expended some of its energy, so the effect on the circuit or device may be different.
