What do you understand by bound and free charges? Explain briefly.
Asked by Topperlearning User | 23rd Apr, 2015, 10:33: AM
In metallic conductors, electrons of outer most shell of the atoms are loosely bound to the nucleus. On applying electric field, they get detached from the atom and move freely inside the metal. These freely moving electrons are called free charges.
