Question

find electrical resistance of 60W lamp operated on 220 volts​

Answer 1

P = VI.

60 = 220 x I,

I = 60 / 220,

I = 0.273A.

V = IR.

220 = 0.273 x R

R = 220 / 0.273

R = 805.86ohms

Answer 2

Answer:

Explanation:

we know that

P=V²/R

P=60 W

V=220 V

R=V²/R

=220*220/60

=806.67 Ω

Hope this helps.
