▪ What is the time taken to generate 3,20,000J heat in a resistor having resistance 2000 Ω when 2 A current flows through it?



{ \huge{ \bold{ \underline{ \underline{ \red{Solution:-}}}}}}



{ \pink{ \bold{GIVEN- }}}



⇝ Heat energy = 3,20,000 J


⇝ Resistance = 2000 Ω


⇝ Current = 2 A


{ \pink{ \bold{TO  \: FIND- }}}



⇝ Time Taken???


{ \boxed{ \bold{ \red{Heat \: energy = {I}^{2} \: R\: T}}}}



where,

➧ I = current

➧ R = Resistance

➧ T = Time taken


▪ substituting the given values in the above formula...



{ \bold{320000J = {(2)}^{2} A \times 2000ohm \times T}}



{ \bold{ \implies{320000 = 4 \times 2000 \times T}}}



{ \bold{ \implies{T= \frac{320000sec}{8000}}}}



{ \huge{ \underline{ \boxed{ \bold{ \red{T = 40sec}}}}}}
