Question

pls help me ques 16 and explain in which of the following circuit a and b heat produced more and why

Answer 1

In B, the heat produced is more because

Due to the large length of wire.

>As resistance increased when the length increases and due to the increase in resistance the HEAT IS ALSO INCREASED.

Answer 2

Circuit B will produce more heat.

Reason:

In both the circuit material of wire is same i.e nichrome.So, both will have same restivity.

But in circuit A lenght of wire is shorter than That of circuit B.

Since,

Resistance of wire is directly proportional to lenght of wire.So, B will have higher resistance which will further result in high heat production.
