2/8/2010 1 Quiz Qn. 1 When a 24 resistor is connected across a 12 V battery, a current of 482 mA flows. What is the internal resistance of the battery? 1. 0.02 2. 0.9 3. 25 4. 49.8 Quiz Qn. 2 Three resistors connected in series each carry currents labeled I 1 , I 2 and I 3 . Which of the following expresses the total value of the current (I T ) in the system? 1. I T = I 1 + I 2 + I 3 2. I T = (I 1 + I 2 + I 3 ) -1 3. I T = I 1 = I 2 = I 3

R 1 2. R 2 3. R 3 4. All have the same current 2/8/2010 4 Quiz Qn. 7 A certain capacitor is charged to 10 V and then at t=0, allowed to discharge through a certain resistor. It takes a time before the voltage across the capacitor reduces to 3.68 V. If I want to reduce the time it takes to reach 3.68 V, then I should decrease 1. the resistor value 2. the capacitor value 3. both of the above...
