Resistance onto external connection to Wheatstone BridgeElectricity and Magnetism Level 3
Electrical is about approximation. You are asked to draw 5 resistors for an electrical circuit. First, connect a \(1\Omega\) resistor in series with a \(4\Omega\) resistor. Second, connect a \(3\Omega\) resistor in series with a \(6\Omega\) resistor. Third, join ends of the two sets of series resistances in parallel by connecting \(1\Omega\) to \(3\Omega\) named point P and also \(4\Omega\) to \(6\Omega\) named point Q. Finally, add a 5th resistor of \(10\Omega\) onto middle of both series sets to form a Wheatstone Bridge Circuit or a bridge circuit.
Ignore all other connectivity, what is the \(EXACT\) resultant resistance across point P and point Q correct to 2 decimal places in \(\Omega\)?
