Задача id12044

The operating voltage of the light bulb, the current-voltage characteristic of which is shown in Figure 11.7, is 3.5 V (the curve ends at a voltage of 4 V - the light bulb burns out). Two such light bulbs are connected in series and connected to a powerful voltage source of 5 V. What is the current strength in value? What resistor R should be connected in parallel with one of the bulbs so that the voltage on the other is 3.5 V? Will any of the light bulbs burn out if this resistor is replaced with another identical light bulb?
