In the circuit shown, & = 90 V, R₁ = 40 , R₁ = 25 , and L= 0.3 H. Switch S is closed at t = 0. Just after the switch is closed, what is the potential difference Ved across the inductor L? Which point, c or d, is at a higher potential? A) |cal = 90 V, point c is at higher potential. B) vedl= 90 V, point d is at higher potential. C) Vedl 144 V, point c is at higher potential. D) Vedl= 144 V, point d is at higher potential. E) None of the above.
