Electricity 22- A coulomb is charge, an amp is current [coulomb/sec] and a volt is potential difference [joule/coulomb]. 23- Short fat cold wires make the best conductors. 24- Electrons and protons have equal amounts of charge (1.6 x 10-19 coulombs each). 25- Adding a resistor in parallel decreases the total resistance of a circuit. 26-Adding a resistor in series increases the total resistance of a circuit. 27- All resistors in series have equal current (I). 28- All resistors in parallel have equal voltage (V). 29- If two charged spheres touch each other add the charges and divide by two to find the final charge on each sphere. 30- Insulators contain no free electrons. 31- Ionized gases conduct electric current using positive ions, negative ions and electrons. 32- Electric fields all point in the direction of the force on a positive test charge. 33- Electric fields between two parallel plates are uniform in strength except at the edges. 34- Millikan determined the charge on a single electron using his famous oil-drop experiment. 35- All charge changes result from the movement of electrons not protons (an object becomes positive by losing electrons) ساعد في نشر والارتقاء بنا عبر مشاركة رأيك في الفيس بوك المصدر: منتدى لغة الروح السيرة الذاتية لي هنا
