lol yeah wikipedia was my first website but i didnt understood that explanations i already found an easy explanations.. thanks anyway.. Superposition Principle The Superposition Principle states that net electric field produced at any point by a system of charges is equal to the vector sum...

Hello I would appreciate if someone can refresh my mind with the principle of superposition..

I am in my second semester of calculus based physics ( electromagnetism ) and like last semester this is my hardest class, and the one that I am struggling with. I spent so much time reading, looking into websites trying to understand the concepts, but when it comes to the test seems like i...

resistors in series share the same current, and resistors in parallel share same voltage is this always true? or exist some exceptions? thanks

my professor said that I = frequency x charge.. and i don't know from where he got that...

OK i think I am missing a really important thing here because I still not sure what formula to use... to derive velocity...

i know the definition of Ampere, but hows that relevant to the question?

A 5.0nC point charge travels in a circle of radius 1.0cm. What is its speed so that the current it generates 1.0mA?. I tried to use I=nqvA, but for some reason it didnt work because i don't know how to calculate n. any hints? thanks!
