19 What is the value of hot resistance of a bulb
rated as 100W/250V? | 100W/250V #tasaran
गर्म प्रतिरोध का मान क्या होगा?
A 31.25 ohm C 312.50 ohm
B 62.50 ohm D 625.00 ohm
there in the third ce​

Answer 1

so,

P= V^2/R , R = V^2/P

for the buland rated as 100W - 250V

the resistance of its filament

R=V^2/P = 250^2/100

=625Ω .

make it brilliant answer
