Answer» $\huge \bold \color{green}{ \underline{ \underline \red{required \: answer : }}}$ GIVEN :- I = 0.5A R = 200ohm TIME = 5min =5×60 = 300seconds now we need to find heat produced in coil.. $\bold { \underline{ \underline{concept}}}$ using joule's law of HEATING.. according to joule's law of heating given by the formula H = I²Rt it is clear that..heat produced in a conductor is directly proportional to :- i) square of CURRENT (I) ii) resistance of conductor (R) iii) time(t) for which current is passed now come to our question so by using formula H = I²Rt $h = {(0.5)}^{2} \times 200 \times 300 \\ \implies \: h = 0.25 \times 60000 \\ \implies \: h = 15000$ hence, heat producing in the coil is 15,000 joule

$\huge \bold \color{green}{ \underline{ \underline \red{required \: answer : }}}$

I = 0.5A

R = 200ohm

TIME = 5min =5×60 = 300seconds

now we need to find heat produced in coil..

$\bold { \underline{ \underline{concept}}}$

according to joule's law of heating given by the formula H = I²Rt

it is clear that..heat produced in a conductor is directly proportional to :-

i) square of CURRENT (I)

ii) resistance of conductor (R)

iii) time(t) for which current is passed

now come to our question

so by using formula H = I²Rt

$h = {(0.5)}^{2} \times 200 \times 300 \\ \implies \: h = 0.25 \times 60000 \\ \implies \: h = 15000$
