Answer:
Circuit 1 = ?
Circuit 2 = Parallel
Explanation:
Since circuit 1 isn't shown on the picture, it's probably a series circuit, but if circuit 1 is a box with symbols around it, then it's a series circuit. But if it has three or more horizontal lines/cables like circuit 2, then it's a parallel circuit - circuit 2 has a second horizontal line with an open switch and lamp.
Circuit 2 is a parallel circuit, as it has branches/horizontal lines (that were explained in the paragraph above).
