What happens to a halogen light bulb specified at 10V DC and 1A (10W) when you connect it to a constant current source that runs on 24V DC and can be regulated up to 0,8A.
You would need to set the current to a maximum of 10W/24V=0.416A to not destroy the halogen light bulb or would there only be a power drawn up to 10V of the halogen bulb maximum voltage rating and a maximum current of 0.8A resulting in only 8W?
