Electronics Worksheet: Electrical Safety

Electronics lesson 2: Electrical safety · Set 639 · 40 questions

Remember (Low, dry, with an adult): Never use mains sockets (about 230 V) for projects; never open chargers or poke into sockets. Water carries current: dry hands, no drinks near circuits, no switches when wet. Use small battery cells with an adult; stop if a part gets hot; keep away from fallen wires, poles and kites near power lines.
