Question

if a current of 2A is passed through a resistance of 250 ohm for 5 minutes. What will be the quantity of heat produced.

Answer 1

Given ,

• Current (I) = 2 amp
• Resistance (R) = 250 ohm
• Time (t) = 5 min or 300 sec

We know that ,

$\boxed{ \sf{Heat \: (H) = {( I)}^{2} Rt}}$

Thus ,

H = (2)² × 250 × 300

H = 4 × 75000

H = 30000 joule

$\sf \therefore \underline{The \: heat \: produced \: is \: 30000 \: joule }$
