Using this diagram: mg. e Given that This circuit runs on the flashbulb of a camera. Circuit is powered by 4 AA batteries each in series that are 1.5 V. The capacitor is C=50 mF when the switch makes contact on the left that is charged through the resistor that is. R1-10 ohm Switch in contact on the right, the capacitor discharges through the flashbulb with a A resistance of R2 = 1m2 that produces light. ● What would be the average power of the light, during the time period of the flash.

Q. 12: A diode is a device that conducts in one direction only. Figure (a) shows the symbol for a diode. When terminal A is at higher potential than B, the diode conducts; it means current flows from A to B. No current flows if B is kept at higher potential. Find the potential difference between terminals C and D after the switch (S) is closed in the circuit shown in Figure (b). D1 B D2 120 V 20 D (a) (b)

Now let's try using a pack of AA batteries (1.2 V output voltage and 0.2 Ohm internal resistance each) to replace the lead-acid battery. In order to match the car lead-acid battery, first, 10 such AA batteries need to be connected in series to form a 12V cell, while 50 such cells need to be connected in parallel (as shown in picture above; the total of 500 AA batteries are used). Find the power that is supplied to the same "car starter" using this pack of AA batteries. (Hint: for the second question, you need to find the total voltage and the internal resistance of the whole pack; you also need to find the resistance of the "car starter"; this can be done using the data of the first part of this problem)
