How calculate the uncertainty in the equivalent resistance?

To calculate the uncertainty in equivalent resistance, first determine the resistance values and their uncertainties for each resistor in the circuit. Use the appropriate formula for combining resistances (series or parallel) and apply error propagation techniques. For series resistances, uncertainties add linearly, while for parallel resistances, use the formula for relative uncertainties to combine them. Finally, express the total uncertainty in the equivalent resistance based on the calculated result.
