Remember (Shape tells the part): Cell: long and short line (long = +). Battery: two or more cells. Wire: straight line. Junction: a dot. Bulb: circle with a cross. Switch: line lifted at a gap. Resistor: rectangle. Capacitor: two equal parallel lines. Diode: triangle against a bar; LED: the same with two arrows out. Circle with M = motor, A = ammeter, V = voltmeter.
