What's the current flow and heat loss?

Post by sacred »

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

Hello Sacred,

Welcome back to Science Buddies.

If you are planning to do a hands-on science project, please tell us more about your plans, including your hypothesis and what sort of experiments you have in mind.

Otherwise, the experts here at Science Buddies can not help with your homework problems!

Thanks!
