In a heater coil 2 A of current passes for 1 second and 400J of heat is produced then the resistance of the coil is 100 Ω.

Explanation:

The electric current in the heater coil, I = 2 A

The time for the flow of current, T = 1 second

The heat produced, H = 400 J  

Let the resistance of the coil be “R” Ω.

We know the formula for the heat produced in a heater coil is given by,

H = I²RT

Substituting the given values  

⇒ 400 = (2)² * R * 1

⇒ R = 400 / 4

R = 100 Ω

Thus, the resistance of the coil is 100 Ω.
