Juku has 12 identical flashlight’s bulbs and a battery. The voltage on the battery’s leads is exactly 5 times bigger than the bulb’s nominal voltage. Juku also found a resistor which has a resistance two times smaller than the resistance of the bulb’s filament in working regimen (the latter was found by dividing the nominal voltage written on the bulb’s socle by the nominal current written on it).
\osa How must be the mentioned components connected to a circuit diagram so that all the 12 light bulbs operate with nominal brightness?
\osa How many times will the total power of the lights increase (or decrease) if one of the bulbs fuses? Do not account for the relation between the resistance of the lamps and the temperature.
