Solve the all parts of given problem:
Problem: An L-R-C circuit has an inductance of 0.470H, a capacitance of 2.20 × 105 F, and a resistance of R.
Part I: What is the angular frequency of the circuit when R=0? Express your answer in radians per second.
Part II: What value must R have to give a decrease in angular frequency of 10.0% compared to the value calculated in Part A? Express your answer in ohms.
I need proficient help in the above problem. Thank you.
