How should I know if my camera is charging (D3200)?

I have a Nikon D3200,

I just got it a few hours ago.

How should I know if my camera is charging?

Will it blink or stay still?

You have to get intimate with Manuel.

The answer is on page 12 of your manual. Download your manual from here.

You don't charge the camera, you charge the battery! It's done outside the camera.
