Question

Please solve this all questions plz...

Answer 1

1) for 4ohm 3and6 are parallel to each and in series with 2ohm
for 1ohm all are in parallel

3) P = VI
4000 =220I
I = 200/11 amp

IR =V
R = 220×11÷200 = 12.1ohm

energy = Pt
= 4000×2×60×60
= 28800000 joule

if 1kwh costs 50paisa then
here is 4kw in sec
so in hour 14400kw
so 7200rs in hour

4) energy = Pt
for tv 250×60 = 15000
for toaster1200×10 = 12000

TV is consuming more energy


2) the question is not clear
