I posted this is the homework section, but it looks like EE homework problems are getting more attention here. I'm pretty sure I've got this right, but I would like to make sure before I hand this is. V=10V DC source I1 = 1H inductor I2 = 2H inductor R = Resistor S= a switch that has been closed for a long time and is opened at t=0 |----I1---R---|----| | | | V I2 S | | | |-------------|----| Am I correct in assuming that opening the switch will have no effect on the current running through I1 and R? In other words, would I be right in assuming that after the switch has been closed for a long time, I2 will become fully charged and can be treated as a short circuit in this simple problem? Thanks for any help.
