Problem

Two resistors,

10\,\Omega

and

40\,\Omega

, are connected in parallel across an ideal

12\,\text{V}

source and operate for

60\,\text{s}

. Determine the thermal energy produced in (a) the

10\,\Omega

resistor and (b) the

40\,\Omega

resistor during this time interval. State both answers in joules.
