HW5.5 Given: Find: 3 1 R ? V 9 2 R ? 2 I 15 3 R ? 3 I 32 4 R ? 4 I A 9 . 2 1 I ? q s t 50 ? Q The resistors in the circuit shown in the diagram have the values listed above (with correct units). The current through R 1 is measured to be I 1 = 2.9 A. (a) Calculate the EMF: (b) Calculate the currents through the other resistors: (Positive current directions are shown by arrows on the diagram.) In a time interval t = 50 s, how much charge flows through the battery? In a time interval t = 50 s, how much total heat Q is generated (all resistors)? Solutions a.) To find V we can use the following formula: 4 3 2 3 2 4 2 4 3 4 3 2 234 1 1 1 1 R R R R R R R R R R R R R 3 2 4 2 4 3 4 3 2 234 R R R R R R R R R R 3 2 4 2 4 3 3 2 4 2 4 3 1 4 3 2 1 3 2 4 2 4 3 4 3 2 1 234 R R R R R R R R R R R R R R R R R R R R R R R R R R R R R total
