Jenna built a completed electrical circuit. jenna’s circuit illustrates what energy transformation?
a. electrical energy decreases over time.
b. electrical energy does not affect heat or light.
c. electrical energy can be transformed only into light.
d. electrical energy can be transformed into both heat and light.

The answer is D. Electrical energy can be transformed into both heat and light.

The correct answer is D.

Explanation:

In the given problem, Jenna built a completed electrical circuit. From the given circuit diagram, it can be concluded that the electrical energy can be transformed into both heat and light.

The electrical energy is used to light bulb and some of the energy is lost due to heat dissipation.

The wires will get heated up and after some time, the bulb will also get heated up. There is a dissipation of the electrical energy in the form heat.

Therefore, the correct answer is D.

12000j is work done

c. magnitude and direction
