Question:

A regular tetrahedron is a pyramid with a triangular base. Six 10.0-Ω resistors are placed along its six edges, with junctions at its four vertices. A 12.0-V battery is connected to any two of the vertices. Find
(a) The equivalent resistance of the tetrahedron between these vertices and
(b) The current in the battery.
