Question

An electric bulb is rated as 100 W,220V. It is used for 5 hours daily Calculat
is daily Calculate
a) It's resistance while glowing
b) Energy consumed in kWh per day​

Answer 1

Answer:

given p=100w

v =220v

according to relation p=vi

100=220×I

100/220=I

10/22=I

i=5/11

according to ohms law

v=I r

220= 5/11 ×r

220×11)/5=r

44×11=r

r=454 ohm

Answer 2

Answer:

exactly that type of question point number B
