*Electric Current is a flowing of electric bucks, consisting of electrons. cardinal types of charges - positive and negative. No charge matter is neutral. Forces between charges atomic number 18 called electrostatic forces. - Like charges repel, unlike attract.
*Rule - charge essential always be conserved, it cannot be created or destroyed.
*Current heedful with an ammeter, voltage measured with a voltmeter.
*Current (I) = Charge (Q) / cadence (t)
*Coulomb (C) is amount of charge passing a superlative when a current of an ampere flows for a second.
*Electricity is conducted only if through material soluble in water when in water, aqueous solutions and in a molten state.
*Material allowing flow of charge is a conductor otherwise an insulator.
*Instrument ingestion to show the existence of a charged object is called a gold flip-flop electroscope, which moves in a certain steering depending on the charge on the object once the leaf has been charged and another charged object is brought near it.
* both main processes for an object to gain charge, other than friction - charging by contact and by induction (charge separation).
*Coulombs Law - Force (F) = (k.q1.q2) / r2
Coulombs unceasing is k, q is charge and r is distance - if more than two charges use vector addition - find the resultant.
*Electric field is produced by a charge or a combination of charges. Forces ar felt depending directly on the test charge pose in the field.
*Electric Field, E = F / q
E = q / 4 Ú0 r2
*Comparison with gravity - Force felt by objects with charge - Force felt by objects with mass. Force relative to size of it of charges - Force proportional to size of masses.
Force inversely proportional to fledge of separation of charges - Force inversely proportional to square of separation...
This is a really good review sheet, few churl problems (ex: tenses and electroscope isnt always gold leaf). Not gona hurt rating tho
I dont screen this as an essay. its more of learning the basic physical scene of physics in micro and macro sense.
when you use formulas where on that point is constant involved, such as the permisitivity, its ideal to write there equavalent.
Some of your explanation are not fantasticly superb only if at least you know the formulas and hopefully the concept of it.
