Consider the circuit shown in the figure (Click "Link to Figure" to access the figure), where L = 5.85 mH and R2 = 475 Q. The switch S can be positioned at either a or b. a) When the switch is at position a, the time constant is 14.9 us. What is R₁ (in ko)? b) What is the current (in mA) in the inductor at the instant the switch is thrown to position b?

Consider the circuit shown in the figure (Click "Link to Figure" to access the figure), where L = 5.85 mH and R₂ = 475 0. The switch S can be positioned at either a or b. a) When the switch is at position a, the time constant is 14.9 µs. What is R₁ (in kQ)? b) What is the current (in mA) in the inductor at the instant the switch is thrown to position b? Link to Figure Submit the current you obtianed in b), with the correct number of significant digits, as your answer. M You are required to show your work for both a) and b) in the file you submit. Round off the final answers to the correct number of significant digits for both a) and b).
