What is the electric potential difference? Electric potential: The electric potential is defined as the amount of work required to move a unit charge from a reference point to any specific point in the presence of an electric field. It is also defined as the electric potential energy per unit...
A point charge q creates an electric potential of +275 V at a distance of 135 m. What is q? A charge of q = - 4.0 \times 10^{-6} is placed in an electric field and experiences a force of 5.5 N [E] a) What is the magnitude and direction of the elect...
The reason has to do with the properties of copper which is a good conductor of charge. Material that are good conductors have loosely held electrons. Movement of electrons occur very rapidly passing from atom to atom along the wire. To move the charge there must be apotential differencebetwee...
aThe electric potential difference due to a point charge is 4.8v at a distance of 4.2cm from the charge.what will be the electric potential energy of the system if a second charge of 6 os placed at that location? 电位差由于点电荷是4.8v在远处4.2cm从charge.what将是系统的电势能,如果6 os...
When an electrical potential difference is applied between two points in a conductive medium, an electric current starts flowing from higher potential to lower potential. The higher the voltage or potential difference, the more the current flows between two points. If two points in a circuit are ...

What is the electric potential at a point distance 100 cm from the centre of an electric dipole of moment 2×10−4C−m on a line laking an angle of 60∘? View Solution What is the electric potential at a point P, distance r from the mid-point of ann electric dipole of moment ...
Charge Storage Process: When voltage is applied, the plates become oppositely charged, creating an electric potential difference. Capacitance Definition: Capacitance is the ability of a capacitor to store charge per unit voltage. Factors Influencing Capacitance: Capacitance depends on the plate area, the...
The potential difference between any two points is then calculated by the expression: {eq}\displaystyle \Delta V=V_B-V_A=kq\left (\frac{1}{r_B}-\frac{1}{r_A}\right ) {/eq} Answer and Explanation:1 In this case, it does not matter that points a and b are not aligned because...
In electrical circuits, power is measured in volts (V), as well as in amperes (A). A volt is the unit of electric potential difference. Another way to explain volt is the force that sends electrons through an electrical circuit to establish an electric current that's measured in amperes....
