Question

Calculate the amount of current flowing through an electric iron of resistance 20 ohm if 1.5 kJ of heat is produced by it in 30 s.

Answer 1

Answer:

this is the answer of your question

Answer 2

Answer:

➡ GIVEN:-

✏ Resistance of the iron = 20 ohm.

✏ Current = 5 ampere.

✏ Time = 30 seconds.

➡ To Find :-

⭐ Formula to be used:-

⏩ Heat produced= I²RT ⏪

➡ SOLUTION:-

Putting all the values, we get:-

Heat produced= I²RT

Heat produced = 25 × 20 × 30

= 15000 joules

Hence, the heat produced in 30 seconds is 15000 joules. ✔
