This circuit, consisting of four resistors, is connected to a voltage source. The value of the resistance marked \(x\) is unknown.
When we accidentally drop a screwdriver across the wires, thus connecting points A and B directly, there is no noticeable change in the current that flows through the circuit.
Calculate the resistance \(x\), in ohms.
