In an electric field 0.90 J of work is required to bring 0.45 C of charge from point A to point B. What is the electric potential difference between points A and B?

The electric potential difference between points A and B is given by the formula V = W/q, where V is the potential difference, W is the work done, and q is the charge. Plugging in the values, we get V = 0.90 J / 0.45 C = 2 V. Therefore, the electric potential difference between points A and B is 2 volts.


What is the value of the potential at points a and b in the following figure?

The potential at point a is 5 volts and at point b is 10 volts in the given figure.


What is the difference between electric potential and electric potential energy?

Electric potential energy is electric energy that is stored in a battery. so all the energy it creates is stored within the battery. It doesn't get used until someone uses it.=Electric potential is the amount of electric potential energy per one coulomb of charge at one point in a circuit compared to the potential energy per one coulomb of charge at another point in circuit also called voltage.=


What is the value of the potential at points a and b in (figure 1)?

The value of the potential at points a and b in Figure 1 is determined by the electric field and the distance from the source of the field.


Electric charge is uniformly distributed on the surface of a spherical balloon. Show how electric intensity and electric potential vary (a) on the surface (b) inside and (c) outside?

(a) On the surface of the balloon, the electric intensity is perpendicular to the surface and is constant. The electric potential varies across the surface with the highest value at the region of highest charge density. (b) Inside the balloon, the electric intensity and potential will be zero since the Gaussian surface does not enclose any charge. (c) Outside the balloon, the electric intensity decreases inversely with the square of the distance from the center of the balloon, while the electric potential also decreases with distance, following a similar inverse square law.

Why does the ball gravitational potential energy increases from point b to a?

Working completely in the dark, I'll take a wild guess and say that point 'a' is higher off the ground or the floor than point 'b' is. I could be wrong. I'd have a better chance of guessing right if I could see the picture.


Clearly distinguish between electric potential energy and electric potential?

Potential difference means the difference in the potentials at two specified points. If "potential" is mentioned without any such qualifier it usually means the potential difference between a point and the "earth" or "grounded terminal". The prefix "electric" is just a reminder we are talking electrically. But the same argument applies equally to gravitational potential.


Why is the kinetic energy the highest at point b in a pendulum?

Kinetic energy is highest at point b in a pendulum because this is the lowest point in the swing where the velocity of the pendulum bob is highest due to the conversion of potential energy into kinetic energy as the pendulum falls. At the highest point, the potential energy is at its maximum and kinetic energy is at its minimum.


Where is the density of the material greater at point A or B Explain why.?

The density of the material is greater at point B because it has a larger mass in the given volume compared to point A. Density is calculated as mass divided by volume, so the greater mass at point B results in a higher density there.


What is single electrode potential?

An electrode potential is the potential difference that develops when an electrode of one element is placed in a solution containing its ions. In a galvanic cell, electricity is produced by the electrode potential of the two metal electrodes and their corresponding electrolytes.


What is the basic unit of measurement for electrical potential?

Potential is measured in volts. The potential at any point is always measured with respect to another point, such as (but not necessarily) earth. So, if the potential at point A measures, say, +12 V with respect to earth, and the potential at point B measures, say, -12 V with respect to earth, then the potential difference between points A and B is +12 V - (-12 V), or 24 volts.


What is need for taking ground connection in circuits?

Practically we take ground at some point or other in a circuit this is done because:-any voltage measuring device gives you only the potential difference so if we desire to measure the voltage at a particular point A in the circuit (say using a multimeter) we are bound to take another point in a circuit B of known potential.ex. if we know that the potential of point B is 4 Vand with the help of voltage measuring device we put one of the leads at A and another lead at B and measure the potential difference between them , let theis value be V volts.VAB=VVA-VB=VVA=V+VBVA=4+Vso, to avoid these confusions we take the point B as ground and arbitrarily chose its potential to be 0 , so that the measures potential difference would actually represent the voltage of the given point A
