transistor
A static switch is a switch that uses the electrostatic current that flows through the human body to power on or off the device.
A: ANY part that uses current to do the work will use some of the input energy to make it operational. this energy is called dissipation of the device and it is wasted as heat
a centrifigal air conditioner
Only a power source and a conducting path between its terminals. If you need the circuit to accomplish anything useful, then there's typically some sort of useful device in the conducting path, that uses power from the source to do whatever it is that you need done.
transformer.
Vaccum tubes use a lot of power and give off heat.
An electric fire is one possibility.

A heat engine that uses heat to do work
a heat pump that uses work to move heat
A device that uses a resistor to transform electrical energy into light and heat is an incandescent light bulb. The resistor, also known as a filament, has high resistance, which causes it to heat up and emit light as a result of the electrical current passing through it.
electric generator
The uses of heat energy is a bulb, sunlight. flashlight, power for your house
Geothermal power
This connecter is used for extra power to the processer.
