For the RL circuit shown in Figure P32.17, let the inductance be 3.00 H, the resistance 8.00 , and the battery emf 36.0 V. (a)

For the RL circuit shown in Figure P32.17, let the inductance be 3.00 H, the resistance 8.00 Ω, and the battery emf 36.0 V.
(a) Calculate the ratio of the potential difference across the resistor to that across the inductor when the current is 2.00 A.
(b) Calculate the voltage across the inductor when the current is 4.50 A
