I have purchased four 100W (120V rated) incandescent light bulbs..?
a) How much current will the bulb consume on the average if I plug it in a 120 V circuit?
b) How much current will the bulb consume in a 12.0V circuit?
(Values are in RMS)
How do I do this problem?
P - Power radiated
e- BB emissivity( 0<e<1)
b- Boltzmann’s constant = 5.670 400(40)×10−8 W/(m^2•K^4).
A – area trough which BB radiates
T- temperature of BB
Tc – temperature of the environment BB radiates
