Hi,
I got a different answer from the book. Please confirm the answer, my answer for question 1 was 0.0417A but the book is 0.046A. I do not know how to do question 2. Thanks
Question 1 An energy saving bulb with 240 V power supply, produces 10 joules of light energy per second. Calculate the current flowing through the bulb.
Question 2 Calculate the heat energy loss of the bulb in one second
What's the current flow and heat loss?
