❏ Given

An electric current of 2A passes through a call of 1ohm resistance for 10 minutes.

❏ To find

calculate the amount of heat produced.

❏ Solution

According to Joules law of heating

This law can be stated as the amount of heat produced in a conductor is

❊ Directly proportional to the square of current flowing through it .

❊ Directly proportional to resistance of a conductor.

❊ Directly proportional to the time .

So, H = I²Rt

where ,

  • H = heat
  • I = current
  • R = resistance
  • t = time

According to the question

  • I = 2A
  • R = 1ohm
  • t = 10min = 10 × 60 = 600sec
  • H = ??

Applying formula

→ H = I²Rt

→ H = (2)² × 1 × 600

→ H = 4 × 600

→ H = 2400 Joules

Hence, the amount of heat produced is 2400 Joules
