Two resistors of 12\Omega and 18\Omega are connected in parallel. This combination is connected in series to another parallel combination of 4\Omega , 6\Omega , and 8\Omega . a. Find the total resistance of the whole combination. b. If the current through the whole combination is 6 A, find the current in each resistor.

Consider the following circuit diagram. The potential difference across the battery is 40.0 volts, and it supplies a current of 5.00 amperes to the circuit. There is a current of of 2.70 amperes flowing through R1. Resistor R2 has a resistance of 5.50 ohms. What is the resistance of R3? Answer in ohms to two decimal places, but do not include units in your answer.
