1. The problem statement, all variables and given/known data In this circuit What will be the reading of the ammeter and that of the voltmeter when: 1. Key S1 and key S2 are open. 2. Key S1 and key S2 are closed. 3. Key S1 is closed and key S2 is open. (Neglect the internal resistance of the source) 2. Relevant equations 3. The attempt at a solution That might be an easy question, but my book doesn't give the solution, and I want to amke sure of my work. Case 1. i = 0 V = 2V Case 2. i = V/R =2/3 A V = Vb - iR = 2 - ((2/3) * 3 = 0 Case 3. Rt = 5+3 = 8 ohm i = V/Rt = 2/8 = 0.25 A V = iR = 0.25 * 5 = 1.25 V So, is my answer correct.
