What about that question in the incorrect/correct section where they gave you two angles and the other angle was the sum of those two angles..
Could that angle have been right-angled?
obtuse-angled?
reflex angle?
straight-angle?
i did what pwoh did! :D
does it matter whereabouts you position the ammeter or battery in the series circuit??? just as long as it is in series it's correct, right??
