The voltage and power ratings of a particular light bulb, which are its normal operating values, are 110 v and 60 w. assume the resistance of the filament of the bulb is constant and is independent of operating conditions. if the light bulb is operated at a reduced voltage and the power drawn by the bulb is 36 w, what is the operating voltage of the bulb?

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
