For times t < 0, the switch is open, as shown. For times t ≥ 0 the switch is closed
closed.(a) Determine the current I(t) around the circuit for t ≥ 0 .(b) Now suppose R = 10 Ω and L = 0.025 H C l l t th ti h I i 90% f it H. Calculate the time when I is 90% of its final value, I(t) = 0.9 E/R. Express the answer in milliseconds.
