Where Is An Electric Field Strongest? The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest. Where is electric field strength greatest? Electric field strength is greatest
What Makes An Electric Force Stronger? The strength of the electric force between any two charged objects depends on the amount of charge that each object contains and on the distance between the two charges. As the amount of charge gets bigger, the force gets bigger, and as the distance between the two charges gets
What Is J In Maxwell Equations? In the last equation, J is the free current density. What is J in electromagnetic theory? The current density vector j is the vector whose magnitude is the electric current density, and whose direction is the same as the motion of the positive charges at M. … For example,
What Is The Direction Of The Electric Field In The Rod? The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. Since electric field is a vector quantity, it can be represented by a
Why Is The Electric Field Inside An Insulator Not Zero? This is attributed to the fact that the electrons are loosely bound to the nuclei and they are free to rearrange themselves until the net field becomes zero. But in an insulator the electrons are tightly bound to the nuclei. So they can resist movement
Why Is The Electric Field Of Dipole Not Zero? Dipole consists of two charges – one positive charge and one negative charge. Those two charges are not at the same point in space. That means that they give some nonzero electric field in total. Can electric field be zero in a dipole? Remember that field
What Is The Direction Of Electric Field Line? These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges. What is
Why Is Del Cross E 0? So del cross E is zero. Because the quantity that it is declared equal to is a time derivative, which will have to be zero in a static problem. Why the curl of electric field is zero? What if curl of a vector is zero? If a vector field
What Total Charge Is On The Inner Surface Of The Spherical Shell? Since the Electric field vanishes everywhere inside the volume of a good conductor, its value is zero everywhere on the Gaussian surface we have considered. So the surface integral is zero. This is the total charge induced on the inner surface. What is
What Is The Direction Of The Electric Field Within The Cell Membrane? outward across the cell membrane inward across the cell. What is the magnitude of the electric field inside of a cell membrane? Electric Potential Across a Cell Membrane In a typical living cell, the electric potential inside the cell is 7.1×10−2 V lower
