Be the first one to answer
Hiiii I am from tutorsduniya.com .We connect students with teachers on facebook,whats app,etc.You can clear your concepts from teachers .You can ask them anything , you like to, be frank with them,...
Charge on proton is equal to the charge on electron and also equal to atomic no, when this quantity put in an electric field, it flows from higher potential to lower potental. the Capacitor, sometimes...
Dear student, Please post a clear imageof the question. The question is not visible properly....
Three concentric spherical metallic shells A, B and C of radii of a,b and c (c>b>a) have charge densities σ, -σ and σ respectively. The potential of shell B isOptions: 1....
The magnitude of force will vary on the placements of the charged conductors. 1. If the are placed parallel to each other at certain distance, then force between them would be of opposite nature, and...
Its well known concept that outside the conducting charged body, finding the electric field, the body behaves as point charge, Here, we are given that charge is spreaded over the ramp surface only, so...
Using the concept of Coulombian force, calculate the magnitude of charge b. In the second case, assume the charge to be 'q' and '4q' and calculate the force between these for the same...
Electron Gun Assembly. The electron gun assembly consists of an indirectly heated cathode, a control grid surrounding the cathode, a focusing anode and an accelerating anode. The sole function of...
Here in the question, charge density is spread over three dimensional arrangement. Since, we are known about the concept of triple integration, so integrating the charge density along x, y and z axes...
The chain is supposed to get rid of any static electricity that builds up within the vehicle by directing it from the frame and tanks and into the ground or road. Preventing the buildup of static...
Dielectric constant will tell us how much conductive it is..... metals are good conductors of heat and electricity, so its K value will be infinity. ….….…...
Calculate the volage drop (as it would be same in parallel combination) in 2 ohm resistance connected in parallel. 2. Then calculate potential drop in next series connected 2 ohm. 3. Add the potential...
As circuit diagram is not mentioned, But i would like to give you the concept about the problem. For maximum power dissipation, internal resistance of the emf must be equal to the external resistance...
Key word in the question is ‘Ideal bettery’ that means no internal resistance. Now use KCL at the junctions for which sum of the current at the junction to be zero. Since Va = 50 V, which...
Here in this question, you write three equations for the potential difference. Vcopper – Viron= i (Riron + Rcopper) --------(i) Calculate the value of current from here and put in the lower...
Net potential difference = E – i r Using this concept for the two circuits, you will get two equations in variable terms (E, e.m.f.) and internal resistance. It wouls be like equations in two...
