If a current of 0.6 ampere is passed through a wire having resistance 15 Omega for 2 minute, calculate the heat generated in the wire in joule. |
|
Answer» Resistance (R) = `15OMEGA` Time (t) `=2xx60s=120s` `"To FIND:Heat (H)"` `"FORMULA:"H=I^(2)Rt` `"Calculation:From formula,"` `H=(0.)^(2)xx15xx120` `=0.30xx15xx120` `=648J.` |
