Problem: Derive the equation for total resistance of this circuit. | | Procedure: 1. Combine the parallel-connect resistors, R_{2} and R_{3}. R_{2,3} = R_{2} || R_{3} | | 2. Include the series-connected resistor, R_{1} R_{T} = R_{1} + R_{2,3} | | 3 Finalize the equation . R_{T} = R_{1} + (R_{2} || R_{3}) | | Solution The total resistance of this circuit is given by . R_{T} = R_{1} + (R_{2} || R_{3}) | | |
