Question

A 9.8-V battery is connected in series with a 37-mH inductor, a 160-Ω resistor, and an open switch.

Part A:

What is the current in the circuit 0.110 ms after the switch is closed?

Express answer in mA

Express your answer using two significant figures.

Part B:

How much energy is stored in the inductor at this time?

Express answer in μJ

Express your answer using two significant figures.

Answer 1

230 mA

R L Now energy stored V I= 1- et 5x37x10 3 (0.23²J - g.gux10 J = gaux1067 = 9 goxloby -990 MJ as given R= 160 ohm L= 37ml = 37x103H V= 9.8 volt - 16ot I - 9.8 378109) 1990 MJ Cine I : 0-6125 (-ė 52422 ty A Icon) = 0425 ( 1-2 ou 32017 I Coim) 06/25 C1-e01756) Answer of part A 230 mA Answer of part-B I CoIlms) = 0.2318 A 990 MF 0.232 A 230 mA

and

990 micro J.

Thanks for asking.
