electrical working

In the case of electrochemical cells, free energy change, D G is related to the electrical work done in the cell. If E is the e.m.f of the cell and n mole of electrons are involved, the electrical work done will be D G = -nFE c e l l , where F is Farada..

The transference of energy may take place as work if the system and surroundings have different pressures. For e.g., suppose a gaseous system is enclosed in a cylinder fitted with a movable piston. If pressure of the system is higher, the piston will be pushed up until the pressure of th..

The spray comb B 1 leaks charges due to action of sharp points and positive charge are sprayed on the belt. As the belt moves up due to induction, negative charges are induced on the spray comb B 2 and an equal positive charge is induced on the farther end of B 2 . Thus, charge shifts to the out..

When pure and dry H 2 gas is passed through the inlet tube, a part of the gas gets adsorbed and the excess bubbles out through the perforations. Between the H 2 gas absorbed on the surface of the metal and H + of the solution, an equilibrium is established and an electrical double lay..

An electric motor is a device which converts electrical energy into mechanical energy. It works on the principle that when an electric current is passed through a conductor placed normally in a magnetic field a force acts on the conductor as a result of which..

Introduction - Appliances used in our day to day life are based on the principles of electricity and magnetism. Electricity is one of the most important sources of energy. Lights, fans, motors, radios and television are some common appliances which work on electri..

Electric Power - Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the..
