No.
The flashlight does.
When you move the switch to the "on" position, it completes the circuit and allows current to flow from the battery to the lightbulb, activating it. When you move the switch to the "off" position, it breaks the circuit, cutting off the flow of electricity to the lightbulb and turning it off. This behavior is controlled by the internal wiring and components of the flashlight.
Like a LED flashlight, the electricity is passing the emitter, turned into light.
You cannot turn on a flashlight without battery inside. That's impossible if the only energy of flashlight is a battery.
Shadows depend on the location of the light source.If, for example, the sun is your light source it will change the size and shape of shadows as it crosses the sky during the day.
