F.2 science (3) (T and F)

Which ine is T(correct) and which one is F(wrong)?
1)We can design our circuit symbols for drawing circuit diagrams.
2)With the help of circuit symbols,the actual electric circuit can be represented easily.
3)We can use curved lines to represent connecting wires.
4)A series circuit has only one path for an electric current to flow.
5)A parallel circuit has only two branches for anelectric current to flow.
