The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Resistance Network 'Use symmetry. imagine applying a voltage between a and c and think about what current will ow in each resistur. b. Assuming R : R', determine the net resistance between the points a and b. c. Now suppose R' = 4.5R, and find the net resistance between points a and b. 0" Rah = abc sin(x) Ox10 Submit Reset Reset All .Think carefully about symmetry
