State the three laws of static electricity. Row 1, Col 1 What is voltage? This is another word for potential difference. 1,2 What is solar, wind, tidal, or hydro? Name one renewable source. 1,3 What are electrons? These subatomic particles of the atom are negatively charged and have EVERYTHING to do with electricity. 1,4 What is the Triboelectric Series or the Electrostatic Series? This useful chart has two different names. Provide one of those names. **Name both for double the points!** 2,1 What is a parallel circuit? This type of circuit provides more than one path for electrons to flow through. 2,2 What is a compact fluorescent light? This is the full name of the more efficient type of light bulb. 2,3 What is a multimeter? This type of meter can measure voltage, current, and even resistance in a circuit. 2,4 What are antistatic mats, antistatic dryer sheets, antistatic wrist straps, humidifiers, grounding straps, or removing carpet (etc.)? Name three different ways to reduce static electricity. 3,1 What is Ohm’s Law V = IR? This fundamental law of current electricity was put into math terms by Georg Simon Ohm. 3,2 What is 50%? A motor for electric-powered Vehicles has an input energy of 150 kJ and an output energy of 75 kJ. What is its percent efficiency? 3,3 What are parallel and series? Voltmeters are attached to a circuit in ___________, while ammeters are attached to a circuit in _______________. 3,4 What is an insulator? This is a type of material that resists or stops electrons from flowing through it. **Double your points by providing 2 examples of this type of material!** 4,1 What are length, cross-sectional area (thickness), material, and temperature? Name the four factors that affect resistance in a wire. 4,2 What are kilowatt-hours? These are the units usually used to measure electrical energy consumption. 4,3 What are fuses and circuit breakers? Name one of two things that act as the first line of defense in your home if something goes wrong in a circuit. 4,4 What are spray painting, photocopiers, and electrostatic generators? Choose one type of technology that uses static electricity and describe how it works to the class. **Add 100 points to your score by naming two other technologies.** 5,1 What is an electrolyte and two electrodes? What are the two main components of an electrochemical cell? 5,2 What are answers will vary? List five appliances found in your home that consume electrical energy even when they are not in use. 5,3 What is a short circuit? This is an accidental low-resistance connection between two points in a circuit, often causing excess current flow. 5,4
