# Power dissipated in a fractal circuit

**Electricity and Magnetism**Level 4

Suppose we take three homogeneous wires with resistance \(R=1~\Omega\) and build an equilateral triangle ABC. Then we take more wires and we inscribe a smaller equilateral triangle inside the original one and we repeat this procedure many times to obtain a fractal circuit as shown in the figure below.
What will be the total power dissipated in the circuit **in Watts** if a \(1~\mbox{V}\) voltage source (or negligible internal resistance) is connected across points A and B?
