SUMMARY
The discussion centers on a Physics Olympiad question involving an electric circuit with resistors of resistance R and a potential difference V applied across points A and B. Key points include that connecting points C and D results in no current flow, effectively creating a short circuit, which leads to no change in potential difference across CO. The resistance across A and B can be calculated using the formula 1/∑R=1/R1 +1/R2, while the resistance across AO requires further analysis based on the circuit configuration.
