Electronics circuits and devices are operate on D.C power supply. But the source of D.C power are mostly batteries and rectifiers. Batteries are really deliver pure D.C supply but they are bulkier and big in size. So we use rectifier circuit for operating Electronic devices. sometimes where backup of supply is needed there both source may present for example in laptops there batteries and rectifier(adapter) both are used.
in electronics we use DC current but in elctrical equipment we use AC current
IT is a type of device used for some application

In the electronics field, a J4 variac is a type of electric energy transfer. It involves the variance of the electric energy.
On average about 65 dollars and month. But this depends on how frequently you use electronics and electrical devices, and what type of electronics you use.
Electronics mostly. Machines, your tv, your computer, your radio, etc.
you use kinetic energy when you eat
You use chemical energy.
they use electrical energy!!
Yes, many electronic gadgets continue to use electricity even though they have been turned off. This energy use is called standby power use.
The type of energy a computer uses is electricty.
mechanical energy
Chemical energy.
thermal energy
