urgent help on these problems! 1. The problem statement, all variables and given/known data Questions 1: http://g.imagehost.org/view/0961/DSC01830 [Broken] Kirchoff's Rules problem on resistors...? Four resistors are connected to a battery with a terminal voltage of 12 V, as shown below. Use Kirchoff's Rules to find the current in each branch of the circuit. Question 2: Physics Matrix problem involving circuits? I have trouble with this problem.. So i have a ti-83 so, does that mean i put it into the matrix. But then what. How do i solve the problem. Could someone give me some steps and explaination on how to do so Thanks!! http://g.imagehost.org/view/0657/DSC01829 [Broken] 2. Relevant equations I think there are the junction rule and loop rules. I1=I2+I3? And use of calculator for matrix? 3. The attempt at a solution 1)So that would me loop and junction rule right?? how would i go about solving this problems, could someone show me the steps to do this? 2)I think I just need calculator help for this(ti-83) but what do they mean by solve it. SOlve what?
