Question

An electric Lamp is mouked 26w 220v.
Iit is used four 10 hours. Calculate its
viesistance while glowing​

Answer 1

Answer:

Given that

Power=26W

Time=10h=10×60×60=36000sec

Energy=Power X Time

⇒Energy=26×36000=936000J

∵1kWh=3.6×10

6

J

Energy consumed in a day in unit of kWh =

3.6×10

6

936000

=0.26kWh

Hence energy consumed in a day is 0.26kWh
