Harder Mathematical Problems
Replacement Resistance ★★★
Here is a little problem from the physical/electro-technical area. Only basic knowledge about electricity and resistance is required, like:
- The replacement resistance of two serial-connected resistances
is 2 Ohm (Rreplacement = R1 + R2, where R1 = R2 = 1). - The replacement resistance of two parallel-connected resistances
is 1/2 Ohm (1/Rreplacement = 1/R1 + 1/R2, where R1 = R2 = 1).
The question: What is the replacement resistance of the circuit below?
