How many the electrical conductivity of Al_(2)Cl_(6) changes on heating ?

When electric current flows through a bulb, the electric enery first changes into light energy and then heat energy.

Answer true or false. An electric bulb converts heat energy into light energy

Explain electrical energy and derive its formula. Obtain Joule.s law of heating.

A 450 muF capacitor is charged to 295 V . Then, a wire is connected between the plates. How many joule of thermal energy are produced as the capacitor discharges if all of the energy that was stored goes into heating the wire?
