Question

An electric bulb of 60 W is used for 6 h per day. Calculate the 'units of
energy consumed in one day by the bulb​

Answer 1

Answer:

Given, The rating of electric bulb = 60 W. Also, it is stated that the electric bulb is consumed for 6 hrs daily. So, in one day it will consume (60×6) watt-hour of energy which is equal to 360 watt-hour. So, your answer is 360 Wh

Answer 2

Step-by-step explanation:

power = 60W = 60/1000 = 0.06 KW

Time= 6 ʜrs

energy = 0.06 × 6

energy = 0.36 KW.h

energy = 0.36 units

∴ Tʜᴇ ᴜɴɪᴛ ᴏғ ᴇɴᴇʀɢʏ ᴄᴏɴsᴜᴍᴇᴅ ɪɴ ᴏɴᴇ ᴅᴀʏ ʙʏ ᴛʜᴇ ʙᴜʟʙ ɪs "0.36 ᴜɴɪᴛs" .
