A wire frame in the form of a tetrahedron ABCD is connected to a dc source The resistances of all the edges of the tetrahedron are equal Choose the correct statement (s)


1.the electric current through DC is zero

2. if we remove anyone of the edges AD, AC, DB or SC, the change in current remain same

3. the current through AB is maximum

4. the change in current will be same if AB or DC is removed
