A. motor
B. generator
C. moving-coil meter
D. battery
Check Answer
The correct answer is D) battery.
A device which converts chemical energy into electrical energy is called a battery. A battery is a device that stores chemical energy and converts it into electrical energy when needed. It is made up of one or more cells, each of which consists of a negative electrode (anode), a positive electrode (cathode), and an electrolyte.
When a battery is connected to a circuit, the chemical reactions within the cells cause the electrons to flow from the anode to the cathode, generating an electrical current. Batteries are used in many different devices, including cell phones, laptops, and automobiles.
A motor is a device that converts electrical energy into mechanical energy. It consists of a coil of wire, an electromagnet, and a stator. When an electric current is applied to the coil, it creates a magnetic field which causes the stator to rotate.
A generator is a device that converts mechanical energy into electrical energy. It consists of a coil of wire, a magnet, and a rotor. When the rotor is turned, it creates a magnetic field which causes the electrons in the coil to move, generating an electrical current.
A moving-coil meter is a device that measures electric current, electric potential difference (voltage), or resistance. It consists of a coil of wire, a magnet, and a pointer. When an electric current flows through the coil, it creates a magnetic field which causes the pointer to move, indicating the value being measured.
