The electric field formula or magnitude of electric field equation for an electric charge Q at distance r from the charge is: E=kQr2 where k is a constant called Coulomb's constant and is equal to 8.987x109Nm2C2, but in solving examples, the value of k will be rounded up to 9.0x109...

Electric field intensity is also known as the electric field strength. The formula for electric field strength can also be derived from Coulomb’s law. This law gives the relation between the charges of the particles and the distance between them. Here, the two charges are ‘q’ and ‘Q’...
Using the equation, we can calculate the total electric field E, which is equal to E1 + E2: Electric Field Lines A small positive test charge q placed at various points near Q would be repelled (or attracted) by Q and would move along the lines. These vectors are called lines of forc...

From the above equation, If x>>a then x2+a2 would be equal to r2 as a on denominator can be ignored and the field becomes that of an electric charge →E=14πϵ0Qx2ˆi So, if point P is far away from the line charge such that a is negligible in comparison to x, then ...

stimulation to the neuron models, the electric potential (Ve) was calculated for each cell by numerically integrating the electric field component along each neural compartment. In the case of uniformly distributed electric fields, the electric potential equation can be simplified as follows (Eq.7)...
The field lines are like stretched rubber bands; hence they will push the conductor in a downward direction, i.e., the force is downward, as shown in figure (b). This example says that the current-carrying conductor in a magnetic field experiences a force. The following equation determines...
