Solve the given parts of following problem:
Problem: Two resistors with R1 = 1,750 and R2 = 3,750 are connected in series.
Part A: If the battery emf is e m f = 18 V, what is the current through each of the resistors?
Part B: What is the equivalent resistance of the two resistors?
Please show all work and steps to find the equivalent resistance of the two resistors.
