Question: You are to compare the electrical requirements of three light bulbs. Use the lighting effect of a 60 w incandescent light bulb as the basis of comparison. For each of the three bulbs, incandescent, CFL, and LED
a) state the electrical power (watts) used and the luminous energy (lumens) output by each of the three bulbs,
b) calculate the current used by each (assume an operating voltage of 120 V),
c) calculate the effective resistance of each,
d) determine the cost of using each bulb for 1 hour.($0.18/kWh)
