Question

The Iceberg Kid, infamous for imposing a deep freeze on whoever disagrees with him, discovers that in his advanced teenaged years his hands constantly feel chilled. As he is a cool physics student, the Iceberg Kid quickly calculates the resistance of the resistor needed to warm his hands. Given that 175 J of thermal energy is generated by the resistor during 9.17 s of operation while connected to a 12.0-V battery, find the correct value of this resistance (and avoid a cold, cold fate).

Explanation / Answer

Let resistance is R

E=(V*V/R)*time=175 J

Where E is energy dissipated in resistance R

144*9.17/R=175

We got R=7.55 ohm
