##### Reference no: EM13544738

The current-density magnitude in a certain circular wire is J = (2.75 × 10^10 A/m^4) r^2, where r is the radial distance out to the wire's radius of 3.00 mm. The potential applied to the wire (end to end) is 60.0 V. How much energy is converted to thermal energy in 1.00 h?
