Some problems on Kirchhoff's law- pls help!
hello.i am stuck with some kirchhoff's law problems. i have attached the problem along with this post. now, all the cells may or may not give current. but atleast the 15V cell has to discharge. (the longer line represents the positive end of the cell.) I'm having problems identifying, in which way current will flow in the circuit? which cell will be discharging and which will not? where will the current flow after starting from the 15V cell. if i could identify the currents, then applying the kirchhoff's loop rule is allright. pls help, I'm really confused. I'm a new member of PF, a good forum indeed. the text above each of the cells denotes the emf and the internal voltage. the two black boxes are resistance boxes with their resistance values given at the side. pls help...
