ypical small flashlight contains two batteries each ving an emf of 1 50 V connected in series with a bulb ving a resistance of 14 2 Submit Request Answer Part C The resistance of real batteries increases as they run down If the initial internal resistance is negligible what is the combined intern resistance of both batteries when the power to the bulb has decreased to half its initial value Assume that the resistance of the bu constant Actually it will change somewhat when the current through the filament changes because this changes the temperature c filament and hence the resistivity of the filament wire W Express your answer using two significant figures VAX 1
