1.	60. An electric heater of power 1000W has has a resistance of 10. The magnitude ofcurrent drawn by the electric heater is :এটা 1000w ক্ষমতাৰ বৈদ্যুতিক ইস্ত্ৰিৰ ৰােধ 102 হলে ইস্ত্রিৰটোৱে লােৱা বৈদ্যুতিকপ্রবাহৰ পৰিমাণৰ হ'ব ?a) 20A b 10A @ 15A d) 13A
Answer» <P>answer option B explanation power =1000 w resistance =10 p= i^2 r 1000 = i^2 r i^2 = 1000/10 =100 I^2 = 100 THEN I = 10 A

Answer»

<P>answer

option B

explanation

power =1000 w

resistance =10

p= i^2 *r

1000 = i^2 * r

i^2 = 1000/10

=100

I^2 = 100

THEN

I = 10 A
