Connecting devices to 12 V battery while charging

Hi,

I'm working on a project for a course I am on. Basically we need to charge a 12 V battery while powering a light bulb and a fan - I know it's strange...

We need to do this using renewable energy from our grounds, I am using hydro power from a fast flowing river. Is it as simple as the below:

Connect alternator / generator to water wheel
Connect alternator to battery
Connect battery to two switches
Connect switches to the fan and light bulb

That seems too easy, do I not need any regulators or something to stop too much power going to the light bulb / fan??

Thanks for any help you can give!

No. Devices only pull the power that is required.

Hmm.
The answer will be in your course material.
Although we can be a good source of info you are safer sorting out the info you are given as it will take you in the direction the course wants you to go .
