The device that uses chemical energy to give charges electric potential energy is a battery because it uses chemical energy which gives off potential electric charges.
An electrometer is a device that detects electric charges by measuring the voltage or current associated with the charges.
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.
A piezo-electric device generates electricity when mechanical stress or pressure is applied to it, causing a displacement of positive and negative charges within the material. This displacement of charges creates an electric potential difference, which can be harnessed to generate electricity.
An ammeter is a device that indicates the presence of an electric current by measuring the flow of electric charges through a circuit.
The device used to maintain electric potential difference is called a voltage source, such as a battery or generator.

A potential electric current can be converted into various forms of energy such as light, heat, mechanical motion, or chemical energy, depending on the nature of the load or device it is powering.
A voltmeter is used to measure electric potential, which is also known as voltage. It is a device that is typically connected in parallel to the circuit or component being tested to measure the potential difference between two points.
A device that can separate positive and negative charges is a capacitor. Capacitors store electrical energy by storing positive charges on one plate and negative charges on the other plate, creating an electric field between them.
When an electric device is connected to a battery, an electric current is produced due to the difference in potential between the positive and negative terminals of the battery. This potential difference, also known as voltage, creates an electrical force that pushes the flow of electric charge (current) through the circuit and powers the device.
If we connect a battery to a device and complete a circuit, current will flow in that circuit and through the device. A battery (in good condition) is an electrical storage device. Most of the ones we are familiar with are chemical cells. There are chemicals inside that would like to react, but cannot unless there is an external circuit through which electrons can move to get from one electrode in the battery to the other. The potential chemical energy in a battery can be converted into electrical energy by completing that circuit. There is a force called voltagethat arises between the electrodes of the battery. And this voltage (electromotive force, or EMF) is the way that the chemical potential energy expresses itself. Because the battery can convert chemical potential energy into electricity owing to that EMF between the electrodes, connecting a circuit across the battery will allow current to flow as the chemical reactions in the battery proceed. A very rough analogy can be drawn by looking at gravitational potential energy. If a bowling ball is sitting on the floor and it is lifted onto a table, its gravitational potential energy has been increased. This is distantly similar to the chemical reactions that want to occur in the battery; they are potential energy, too. If the bowling ball rolls off the edge of the table, the potential energy is converted into kinetic energy by gravity. When we hook up an external circuit to the battery, the chemical potential energy (expressed as voltage) drives electrical current through that circuit and the device in it. The circuit here is composed of conductors and the device. Electrons in the conductors are hanging around in the conduction band, and if a voltage is applied, those electrons will begin moving in response. The device must be conductive to some extent, and it, too, will have this electron current flowing through it. The battery has been connected to a circuit and drives current through that circuit. The chemical potential energy in the battery is converted into electrical energy in the circuit and the device connected to it.
Fuel is a form of potential energy stored in chemical bonds. When the fuel is burned, its chemical potential energy is converted into thermal energy and then into kinetic energy to power an engine or device.
