Which is an example if electrical energy a. a light bulb giving off heat but not light b. negatively charged particles causing a bulb to light up c. the light from a star seen in the sky

A. A light bulb giving off heat but not light

in this case electrical energy is converted into thermal energy.

B. Negatively charged particles causing a bulb to light up

In this example the electrostatic energy is converted into light energy.

C. The light from a star seen in the sky

Here it is the phenomenon of propagation of light.

So example A) is the correct example for electrical energy.
