Solve the all parts of given question:
A 42.3 ohm resistor and a 91.2 ohm resistor are connected in parallel, and the combination is connected across a 120V dc line.
Part A: What is the resistance of the parallel combination?
Part B: What is the total current through the parallel combination?
Part C: What is the current through the 42.3 ohm resistor?
Part D: What is the current through the 91.2 ohm resistor?
I need help to find the resistance of the parallel combination.
