The power rating on a light bulb indicates

the vitality looking at burning bulb reveals how much power it
V= rated existing = 120 Volts
P = rated power = 75 watt
of 120 V?
P’ = real power dissipated = V’2/R =
P = rated power = 75 watt
A)
rated at 75 W, if instead we link it to a potential enhancement

Roentgen = rated resistance = V2/P = (120)2/75 =
V’ = existing made use of = 120 Volts
existing of 120 V (this standing will not constantly imply the light bulb
rated at 75 W, if instead we link it to a potential enhancement
V= rated existing = 120 Volts
