So basically due to the electric field of the positive charge at the center, an equal amount of charge $-Q$ will appear on the inner surface of the hollow sphere and that will leave behind a charge equal to $+Q$ on the outer surface.

Define stopping potential (cut-off potential) with reference to photoelectric effect. Stopping potential or cut-off potential is defined as the required potential for stopping the removal of an electron from a metal surface when the incident light energy is greater than the work potential of the metal on which the incident light is focused.

(b) As we discussed in Exploration 27.2, the maximum kinetic energy of the emitted electrons is related to the minimum voltage across the two plates needed to stop the electrons from reaching the second plate (this is known as the stopping potential ).

A current transformer is a device which is used for the transformation of current at a higher value to a lower value with respect to the earth potential. It is used with the AC instruments for measuring the high value of current. The line current is too high, and it is very difficult to measure them directly.

An electric dipole is a pair of equal and opposite charges q and –q separated by a distance denoted as d. The formula for electric dipole moment is p = Qd. Molecules mostly have their positive and negative charges lying at the same place and therefore, their dipole moment is zero. The line along the direction of an electric dipole is called.

Potential gradient (K) is defined as a potential difference per unit length of wire. It is measured as, `”V”/”L” = “ER”/ (“L” (“R” + “r”))` where V = Potential difference between two points L = Length (distance) between two points; Explanation: A potentiometer consists of a long wire AB of length L and resistance R having uniform cross-sectional.

The potential energy of a particle varies with distance x from a fixed origin as U = A√x/x2+B, where Aand B are the dimensional constants, then find the dimensional formula for AB. Byju's Answer. Standard XIII.

Figure 5 shows a system of capacitors, where the potential difference across ab is 38.0 V. (a) What is the equivalent capacitance of this system between a and b? (b) How much charge is stored by the Physics Capacitors Solutions Two 10 μF parallel plate capacitors are connected in parallel.

A. By which method are the appliances connected? B. What must be the potential difference across individual appliances?

In equation form, the electric potential difference is. The standard metric unit on electric potential difference is the volt, abbreviated V and named in honor of Alessandro Volta. One Volt is equivalent to one Joule per Coulomb. If the electric potential difference between two locations is 1 volt, then one Coulomb of charge will gain 1 joule.
