    Electrical Field Maxwell developed an approach to  discussing fields An  electric field  is said to exist in the  region of space around a charged  object When another charged object enters this  electric field, the field exerts a  force  on the  second charged object

    Electric Field, cont. A charged particle, with  charge Q, produces an  electric field in the  region of space around  it A small  test charge , q o placed in the field, will  experience a force

    Electric Field Mathematically, SI units are N / C Use this for the magnitude of the field The electric field is a vector quantity The direction of the field is defined to be the  direction of the electric force that would be  exerted on a small positive test charge placed  at that point 2 e o k Q q r = = F E r r

    Direction of Electric Field The electric field  produced by a  negative charge is  directed toward the  charge A positive test  charge would be  attracted to the  negative source  charge

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
