Cells and batteries supply direct current (\ (dc\)). This means that in a circuit with an energy supply from a cell or battery, the current is always in the same direction in the circuit. The oscilloscope gives the following display for the electricity from the mains. Oscilloscope trace of the voltage from an alternating supply.
A battery stores electrical potential from the chemical reaction. When it is connected to a circuit, that electric potential is converted to kinetic energy as the electrons travel through the circuit. Electric potential is defined as the potential energy per unit charge (q).
The electrical driving force across the terminals of a cell is known as the terminal voltage (difference) and is measured in volts. When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
(This is known as the “equivalent voltage” for the battery combination). B4. Measure the voltages: • Use a DMM set to the 20V scale to measure the voltage drop across the bulb, and the voltage across the two batteries. (DMM stands for digital multi-meter and is another name for the electrical multi-meter you used in the circuits lab).
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.

What type of current is supplied by the battery in a flash light?
The type of current supplied by the battery in a flashlight is direct current (DC). Direct current flows in only one direction, from the positive terminal of the battery to the negative terminal. In contrast, alternating current (AC) periodically changes direction and is commonly used in electrical systems that are connected to a power grid.
