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.

Text Solution

Verified by Experts

The correct Answer is:
Heat generated in the wire is 648J.
`"Given: Current (I) = 0.6 A,"`
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.`
