current in voltaic cell

The mass of substance deposited is directly proportional to the quantity of current passe..

It is a device used to convert the chemical energy produced in a redox reaction into electrical energy. Example: The redox reaction between Zn and CuSO 4 ..

In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reaction. In a simple voltaic cell a zinc ..

The fact that chemical reactions produce electrical effects was discovered accidentally in 1791 by Luigi Galwani, professor of anatomy at the University of Bologna, Italy. He found that an electric current flowed across two dissimilar metals between which was a moist substance. In his cas..

If the current flows always in the same direction, it is called 'direct current'. Direction current is represented as DC or dc. The current derived from a cell or a battery is direct current - since it is unidirectional. The positive..

Introduction - Do we use dry cells for operating electrical appliance? It is not impossible to tap continuous supply of energy from electrochemical cells. Electrical circuits in homes, factories and offices receive such energy form local power companies. In most countries the en..
