Question

Define Joule's law and what will happen with heat produced by the circuit if current becomes double?​

Answer 1

Answer:

a)Joule’s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy.

The joule’s first law shows the relationship between heat produced by flowing electric current through a conductor.

Q = I2 R T

Where,

• Q indicates the amount of heat
• I show electric current
• R is the amount of electric resistance in the conductor
• T denotes time
• The amount of generated heat is proportional to the wire’s electrical resistance when the current in the circuit and the flow of current is not changed.
• The amount of generated heat in a conductor carrying current is proportional to the square of the current flow through the circuit when the electrical resistance and current supply is constant.
• The amount of heat produced because of the current flow is proportional to the time of flow when the resistance and current flow is kept constant.

b) Heat will also get doubled because current flowing through the conductor is directly proportional to heat
