How do you fix a Ipad charger?

you can go buy a new one or I you don't have money you can just use duct tape and tape it together

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

i do not get it   at all
