Electric fields and equipotentials: field direction and magnitude

1. 1Arrows go from [blank_start]positive[blank_end] to negative
   To work out the field at A due to 2 point charges, resolve in x and y [blank_start]separately[blank_end] and use Pythagoras to get the [blank_start]magnitude[blank_end], then [blank_start]tan[blank_end] function to get direction
   [blank_start]Equipotentials[blank_end] are surfaces made up from points in space that have the same value of potential
   Circulation law - a path that forms a complete circuit has no [blank_start]work[blank_end] [blank_start]done[blank_end]
