Question

does there exist electric field in the electrolyte of cell when the circuit is closed and steady current passes through it explain​

Answer 1

to maintain the study current a potential difference V across the terminal of the cell is required since E=V/d

where D is the distance between two electrodes so and electric field in electrolyte of cell exist

Answer 2

Electric Current

The Battery

A battery is a device that converts chemical energy directly to electrical energy.

LEARNING OBJECTIVES

Describe the functions and identify the major components of a battery

KEY TAKEAWAYS

Key Points

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.

The voltage or potential difference between two points is defined to be the change in potential energy of a charge q moved from point 1 to point 2, divided by the charge.

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.

Key Terms

battery: A device that produces electricity by a chemical reaction between two substances.

current: The time rate of flow of electric charge.

voltage: The amount of electrostatic potential between two points in space.


Symbol of a Battery in a Circuit Diagram: This is the symbol for a battery in a circuit diagram. It originated as a schematic drawing of the earliest type of battery, a voltaic pile. Notice the positive cathode and negative anode. This orientation is important when drawing circuit diagrams to depict the correct flow of electrons.

A battery is a device that converts chemical energy directly to electrical energy. It consists of a number of voltaic cells connected in series by a conductive electrolyte containing anions and cations. One half-cell includes electrolyte and the anode, or negative electrode; the other half-cell includes electrolyte and the cathode, or positive electrode. In the redox (reduction-oxidation) reaction that powers the battery, cations are reduced (electrons are added) at the cathode, while anions are oxidized (electrons are removed) at the anode. The electrodes do not touch each other but are electrically connected by the electrolyte. Some cells use two half-cells with different electrolytes. A separator between half-cells allows ions to flow, but prevents mixing of the electrolytes.
