Electrical pressure, called "electro-motive force" (EMF), is what causes current to flow in an electrical circuit. EMF is measured in volts.
Pressure and the quantity of electricity transmitted can be considered analogous to pressure and quantity of water flowing in pipes: the longer the distance, the higher is the pressure (called the "voltage" for electricity) that is necessary to pump the flow of water (called the "flow of electrical charge, which is also known as the "electric current").
That is why, for long distance transmission, high pressure (voltage for electricity) is required, failing which, the current - and therefore the power - will not reach the intended destination. Instead, it will be lost (also called "dissipate") along the way.
We can think of electrical current as the quantity of electricity which will be drawn from the pipeline (= cables for electricity) at the pressure (= voltage) required.
A dry cell produces direct current (DC) when a chemical reaction within the cell generates a flow of electrons in one direction. This current flows from the negative terminal to the positive terminal of the cell.
Charges that provide current in a cell are produced by the chemical reactions that occur between the electrolytes and electrodes within the cell. These reactions create a flow of electrons, which is what we refer to as electric current.
Stored Chemical energy, which is transfered into the electrical item, pushing the negative charge which is electrisity.
A photogalvanic cell is a type of electrochemical cell that generates electrical energy from light. It typically consists of a photoactive electrode, an electrolyte, and a counter electrode. When light is absorbed by the photoactive electrode, it initiates a chemical reaction that produces a potential difference and drives an electric current.
A carbon-zinc dry cell supplies electric current by converting chemical energy into electrical energy through a chemical reaction between the carbon rod (negative electrode) and the zinc can (positive electrode). When connected in a circuit, electrons flow from the anode (zinc) to the cathode (carbon), generating a flow of electric current. This current can power a CD player by providing the necessary energy to operate its electronic components.
a primary cell is an electric cell that produces current by an irreversible chemical reaction
The panel itself produces DC and if it is connected to mains electricity it needs a separate converter to change the current to AC.
Either the cell e.g. a battery, if one is included in the circuit. Or a generator such as a dynamo
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.
A chemical cell or strings of cells called a battery.
A dry cell produces direct current (DC) when a chemical reaction within the cell generates a flow of electrons in one direction. This current flows from the negative terminal to the positive terminal of the cell.
A battery produces an electric current by converting chemical energy into electrical energy. The chemical reactions inside the battery drive the flow of electrons through an external circuit, generating electricity.
Charges that provide current in a cell are produced by the chemical reactions that occur between the electrolytes and electrodes within the cell. These reactions create a flow of electrons, which is what we refer to as electric current.

The parts of a cell that work together to produce an electric current are the anode (positive terminal), cathode (negative terminal), and electrolyte. The anode releases positively charged ions into the electrolyte solution, while the cathode receives these ions and releases negatively charged ions. The flow of ions between the anode and cathode through the electrolyte creates an electric current.
