I need help!!! I please answer with procedures and final results In a circuit the switch is open for a very long time and then closed at t = 0. if, V = 3.5 V, R1 = 848 omega , R2 = 548 omega , L = 7.2 mH ). R1 is in series with R2. a) What is the current through R1 immediately after the switch is closed? ____________________ A b) What is the current through R2 immediately after the switch is closed? ____________________ A c) What is the voltage across the inductor immediately after the switch is closed? ____________________ V d) After the switch has been closed for a long time what is the current through R1? ____________________ A e) After the switch has been closed for a long time what is the current through R2? ____________________ A f) After the switch has been closed for a long time what is the voltage across the inductor? ____________________ V g) The switch is now opened. What is the current through R11 immediately after the switch is opened? ______________ A

Explanation / Answer

you have not given figure .... i m assuming that R1, R2 and L are connected in series with 3.5 V battery .......... then ....... a) current = 0 ... immediately switch is closed inductor will act as an open circuit b) current = 0 ... immediately switch is closed inductor will act as an open circuit c) voltage =0 ... immediately switch is closed inductor will act as an open circuit d) current = V/(R1+R2) = 3.5/1396 = 2.5 m A ............... e) current = 2.5 mA ................. f) Voltage =0 ,,, because inductor will act as an simple wire having zero potential .... g) current = 2.5 mA ,,, inductor will appose to any change in current ....
