Answer:-

  • Resistance=R=200ohm
  • Current=I=1A
  • Heat=160000J=H
  • Time=t=?

According to Joules law

\boxed{\sf H=I^2Rt}

\\ \sf\longmapsto 160000=1^2\times 200t

\\ \sf\longmapsto 160000=200t

\\ \sf\longmapsto t=\dfrac{160000}{200}

\\ \sf\longmapsto t=\dfrac{1600}{2}

\\ \sf\longmapsto t=800s

\\ \underline{\boxed{\bf{\therefore Time=800s.}}}
