Question

The resistance of a wire is 100 ohm.If it carries a current of 1Amp for 10seconds the heat produced will be _______. ​

Answer 1

Question :-

• The resistance of a wire is 100 ohm.If it carries a current of 1Amp for 10seconds the heat produced will be ___.

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

Given that :-

• Resistance of a wire = 100 ohm
• Correct flowing through it = 1 A.
• Time = 10 sec.

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

To find :-

• Heat produced

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

Formula to be used :-

• Heat = I²Rt

ㅤ‎‎‎‎ㅤㅤWhere, I = current

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎R = resistance

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎t = time.

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤ

Solution :-

Heat produced in circuit = I²Rt

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎ㅤㅤㅤㅤ= (1)² × 100 × 10

ㅤ‎‎‎‎ㅤㅤㅤㅤㅤㅤ‎‎‎‎ㅤㅤㅤㅤ= 1000 Joule.

Therefore, heat produced = 1000 Joule.
