In the figure, suppose that ε = 51.3 V, R = 247 Ω, and L = 0.197 H. With switch S2 open, switch S1 is left closed until a constant current is established. Then at time t = 0 s, S2 is closed and S1 opened, taking the battery out of the circuit. What is the potential difference between points b and c at t = 3.58 × 10-4 s?  Write your answer in the units of volt (V) in decimal form with one digit to the right of the decimal point (e.g. 5.3).  Do not include units or sign in your answer; just write the numerical value.
