The short form of Electromotive force is EMF. According to the law of Faraday “EMF” is a voltage generated by a magnetic force. But in classic physical sense EMF is not a force as it is measured in term of volt, not Newton. External Work expanded per unit of charge to produce an electrical potential difference accross two open-circuited terminal is known as Electromotive force. Here, you can find some questions related to “Electromotive force” and their answers: Questions: 1. The emf of a galvanic cell with...

Those conduction which involve the movement of ions is called electrolytic conduction. Example of electrolytic conduction is solution of Nacl and water. It can also be said as, “the condition in which the electrical current flows through the ions on a solution or pure liquid.” In this artcle you can find some questions related to “Electrolytic conduction” and their answers: Questions: 1. The best conductor of electricity is a 0.1 M solution of: (a) Acetic acid (b) Boric acid (c) Propionic acid (d) ...
