static electricity Flashcards
what is static electricity
a material that has an uneven distribution of positive and negative charge, due to contact, friction or induction
what is coulomb’s law
“the magnitude, of the electrostatic force of attraction, or repulsion, between two-point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them”
coulomb’s law equation?
Qv1Qv2
F=K ————
d^2
where k =9.0 x 10^9 Nm^2/C^2 the universal electric constant
what happens between the anode and cathode if you pass an electrical charge between them in an electrolyte
the Anode attracts neg ions (anions) the Canode attracts pos ions (cations) and new substances are formed at each
what is electrolysis?
the passing of an electric current through a liquid causing chemical decomposition
what is gas discharge
the conduction of electricity via a gas, often accompanied by light
what is produced when an electric current passing through water decomposes the water
hydrogen and oxygen
what carries a charge through an electrolyte?
ions carry the charge rather then electrons
what law can be used to calculate the force of repulsion?
coulomb’s law
