HWK 35 (Parallel Circuits: SOLUTIONS) (due Monday 4/16/07) SAR Physics AM Kolchin Read chapter 35: sections 35.6 through 35.7 (pages 555-558) Answer questions: 11, 12, and 13. Do this worksheet . You must show your work using an equation and units in order to get full credit. Rules for Parallel Circuits : 1. In a parallel circuit, current divides to flow through the diferent branches. The total current equals the sum of the currents in all of the branches. 2. The voltage drop across each resistor is the same. 3. Ohm’s Law ( V = IR or I = V/R ) can be applied between any two points in a circuit. 4. The resistances can be replaced by an ”equivalent resis- tance” that leaves the current unchanged. It is Found as Follows: 1 R EQ = 1 R 1 + 1 R 2 + 1 R 3 + .... 1
