90. Three identical lamps, each of which is designed for the voltage U = 4V are connected in parallel and are connected via a resistor to the power source with the EMF E = 8V. The lamps are lit in a nominal mode (i.e., in operation the voltage at which U1 and output current in each R1 is the same as written on their base. How many times will be different power of the current in each of the lamps as compared to the nominal, if one of them burns out, and the remaining resistance be the same?
