A generator is on daily use and in the process, ten 60 W and five 40 W tungsten bulbs are on for the same time interval. the energy consumed daily is?
A
0.96 kWh
B
1.92 kWh
C
9.60 kWh
D
19.20 kWh
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Energy consumed = power x time
= (60 W x 10 + 40 W x 5) x 24 h
= (600 W + 200 W ) x 24 h
= 800 W x 24h = 19200 w h
= 19.2 kWh
