Compute all parts of given question:
Question: An 81.0- resistor is connected in parallel with a 174.3- resistor. This parallel group is connected in series with a 21.2-resistor. The total combination is connected across a 15.1-V battery.
Part A: Find the current dissipated in the 174.3- resistor?
Part B: Find the power dissipated in the 174.3- resistor?
I want you to clarify the physics in this above problem.
