A skeleton tube is made of 12 wires each of resistance `ROmega` is connected to a cell of emf E and of negotiable internal resistance. Use Kirchhoff's laws to find the resistance between:- diagonally opposite corners of the cube.

A skeleton tube is made of 12 wires each of resistance ROmega is connected to a cell of emf E and of negotiable internal resistance. Use Kirchhoff's laws to find the resistance between:- diagonally opposite corners of the same face of the cube is across face diagonal.

A skeleton cube is made of 12 wires, each of resistance R. The resistance between any two adjacent comers of the cube is

Twelve wires ,each of resistance 6 Omega are connected to form a cube. The effective resistance between two diagonally opposite corners of the cube is

A lead resistance R is connected across a cell of emf E and internal resistance r. If the closed circuit p.d. across the terminals of the cell is V the internal resistance of the cell is.

A voltmeter having a resistance of 50 Omega is connected across a cell of e.m.f. 2V and internal resistance 10 Omega . The reading of the voltmeter,

Write relationship between e.m.f. of a cell and its internal resistance.

A wire of length 100 cm is connected to a cell of emf 2 V and negligible internal resistance. The resistance of the wire is 3 Omega . The additional resistance required to produce a potential drop of 1 milli volt per cm is

A voltmeter has a resistance of 100 Omega . What will be its reading when it is connected across a cell of emf 2 V and internal resistance 20 Omega ?
