Answer:
According to the question,
- Resistance = 120 ohms
- Potential Difference = 12 V
⇒ Current = 12 V / 120 ohms
⇒ Current = 0.1 A
Now we know that, Heat is defined as:
⇒ Heat = I²RT
- I = Current Flowing
- R = Resistance
- T = Time of flow of current
Substituting the values we get,
⇒ Heat = 0.1 × 0.1 × 120 × 30 × 60 = 2160 J
Hence the amount of heat produced in the nichrome coil is 2160 J or 2.16 KJ.

GIVEN:-
120 Nicrome
Added 12 Volt Battery.
Current Flows 30 Minutes.
TO FIND:-
Calculate the Amount of Heat Produce.
SOLUTION:-
Current = Potential DIfference/Resistance
According to the question,
Resistance = 120 ohms
Potential Difference = 12 V
⇒ Current = 12 V / 120 ohms
⇒ Current = 0.1 A
Now,
Heat is defined as:
⇒ Heat = I²RT ( Formula ).
Substituting the values we get,
⇒ Heat = 0.1 × 0.1 × 120 × 30 × 60
= 2160 J
