Figure shows a cube made of 12 resistance across a cube edge ab.

The resistance across A and B in the figure below will be

Twleve equal wires , each of resistance r ohm , are connected so as to form a frame of a cube . An electric current enters this cube at one corner and leaves from the diagnalyy opposite corner . Calculate the total resisatance between the corners .

How many spherical balls can be made out of a solid cube of lead whose edge measures 44 cm and each ball being 4 cm in diameter.

ABC is a triangle made up of wire.The resistances of the sides AB, BC and CA are respectively 40, 60 and 100Omega The equivalent resistance between the points A and B is :

PQRS is a square of side l m long and is made up of wire of resistances r Omega//m . Similar wires are connected across the diagonals PQ and QS show that the effective resistance of the framework between the corner P and R is (2 -sqrt3)lrOmega .

A point charge of 12muC is placed at the centre of a cube of side 1m. What will be the electric flux passing through each face of the cube?

Twelve equal wires, each of resistance r, are joined to form a skeleton cube. The current enters at one corner and leaves at the diagonally opposite corner. Find the total resistance between these corners.

State True or False- If the length of each edge of a cube is twice of that 1st cube, then the volume of this cube is 4 times more than that of the 1st cube.
