Which energy transformation takes place when a lamp with a light bulb is plugged into a working wall socket?(1 point)

The energy transformation that takes place when a lamp with a light bulb is plugged into a working wall socket is electrical energy to light energy.

ideally yes :

However unfortunately a lot of the electrical energy gets transformed to heat energy even with modern LED bulbs :(

Correct, you are absolutely right. In reality, when a lamp with a light bulb is plugged into a working wall socket, some of the electrical energy is converted into light energy, but a significant portion is also transformed into heat energy. This is due to the inefficiencies and resistance in the circuit and the heat generated by the filament in traditional incandescent bulbs or the internal components in LED bulbs.
