Question

The resistance of a wire is 100Ω .If it carries a current of 1 A for 10 seconds, the heat produced will be …… .​

Answer 1

Explanation:

Resistance of wire ( R ) = 100 ohms

Current ( I ) = 1 A

Time ( t ) = 10 s

\underline{\:TO\:FIND}

TOFIND

Heat produced = ?

\underline{SOLUTION}

SOLUTION

We know that

Heat produced = I²Rt

= 1² × 100 × 10

= 1000 J

< b > So the heat produced is 1000 J<b>Sotheheatproducedis1000J
