if the external circuit is replaced by a source of electricity that opposes the voltaic cell, the electrode reactions can be reversed.Now,the external source pushes the electrons in the opposite direction and supplies energy or work to the cell so that the reverse non-spontaneous reaction occurs.

Why is it correct to classify the fuel cell that you have costructed as a voltaic cell?
A fuel cell operates based on the same principle as a voltaic cell; it generates electricity through a chemical reaction. In a fuel cell, chemical energy from the fuel is directly converted to electrical energy without combustion, making it similar to a voltaic cell that uses redox reactions to generate electrical energy. Therefore, it is correct to classify a fuel cell as a type of voltaic cell.
What is voltaic cell?
A voltaic cell is an electrochemical cell that generates electrical energy through a spontaneous redox reaction. It consists of two half-cells connected by a conductor, where oxidation occurs at one electrode (anode) and reduction at the other electrode (cathode), producing an electric current.
What must be the sign of the standard cell potential (cell) for a redox reaction to be spontaneous?
For a redox reaction to be spontaneous, the standard cell potential (cell) must be positive.
Which of the following factors does not affect the voltage produced in a voltaic cell?
The distance between the electrodes does not affect the voltage produced in a voltaic cell. This voltage is primarily determined by the nature of the redox reaction occurring at the electrodes and the concentrations of the reactants involved.
In a voltaic cell chemical energy is converted to?
In a voltaic cell, chemical energy is converted to electrical energy through redox reactions that occur at the electrodes. This conversion of energy is driven by the flow of electrons from the anode to the cathode through an external circuit, allowing for the generation of an electric current.
An electrolytic cell is different from a voltaic cell because in an electrolytic cell?
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.
How does a voltiac cell work?
The voltaic cell work under the principle of redox reaction which involves the transfer of electrons from one electrode to another.
Difference between daniell cell and voltaic cell?
A Daniell cell is a specific type of voltaic cell that utilizes a zinc anode, a copper cathode, and a solution of copper sulfate and zinc sulfate to generate electricity through redox reactions. Voltaic cell is a broad term encompassing any electrochemical cell that converts chemical energy into electrical energy through spontaneous redox reactions. Daniell cell is an example of a voltaic cell.

What type of energy conversion takes place in a voltaic cell?
Chemical energy is converted to electrical energy in a voltaic cell through redox reactions that occur at the electrodes. The chemical reaction releases electrons that flow through an external circuit, creating an electrical current.
