The amount of electrical energy that is involved in this transformation is 120 J. The correct option is D.

What is electrical energy?

Electrical energy is the energy that is formed by converting the electric potential energy into electric energy. Energy can also be described as the transfer of electrons from one atom to another.

When heat energy and light energy are connected, then electric energy is produced. The law of conservation of energy is also applied here.

Given the Light energy (L) = 100 J

Heat energy (H) = 20 J

Electrical energy, (E) = ?

The equation to solve the electrical energy is:

E = L + H

Putting the value in the equation

E = 100 + 20 = 120

E = 120 J

Thus, the correct option is D. 120 J.
