The efficiency for incandescent light bulbs is typically about 14 lumens per watt (lm/W) and that for LED bulbs is typically about 90 lm/W.
Use Ohm’s law to calculate the total light output in lumens of each type of bulb if the incandescent bulb has resistance of 10 Ω and the LED bulb has resistance of 2 Ω and each are supplied with a current of 2 A.
Question 1 options:
Incandescent: 230 lm. LED: 360 lm.
