Symbol Guide
Cells have a long line (+) and short line (-). Batteries are multiple cells.
Fixed resistors (rectangle) vs Variable resistors (rectangle with diagonal arrow).
LDRs have circles with arrows pointing in; LEDs have arrows pointing out.
Ammeters must be in series; Voltmeters must be in parallel.
Exam Skill: If you see a circle with an X, it's a lamp (bulb). If the circle has a V or A, it's a measuring instrument.
