 What does a capacitor do? Has the capacity to store charge and enegy. What is the capacity of a capacitor? C = Q/V What is the capacity of a parallel plate capacitor? C = Aε/d If inside of a capacitor distance "d" between two plates is made smaller, what happens to the Capacity? Increases What is the unit for Capacitors? C/V aka Farad What is 1012? Terra What is 109? Giga What is 106? Mega What is 103? Kilo k What is 10-3? Milli m What is 10^-6? Micro υ What is 10-9? Nano n What is 10-12? Pico p What is the equation for Spherical Capacitors? 1 k(1/Rinner - 1/Router) What is the equation for Cylindrical Capacitors? L 2k ln(Rlarge/Rsmall) R is the Radius What would increase the capacitance of a parallel plate? Move the plates closer together If the voltage between the plates of a parallel plate capacitor is doubled, the charge on the capacitor does what?
