What joules law of heating
Answers
Answer:
Joule’s Law of Heating
The heat that is generated because of the current flow in an electric wire is described in Joules. The mathematical expression of Joule’s law is as explained below.
Joule’s first law
The joule’s first law shows the relationship between heat produced by a 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 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.
hi mate,
we know that the Joule Heating Definition
Joule heating (also referred to as resistive or ohmic heating) describes the process where the energy of an electric current is converted into heat as it flows through a resistance.
Answer: Joule's law of heating states that , "The heat produced in a resistor is directly proportional to (1) square of current (I^2) (2) resistance of the resistor (R) and (3) time for which the current flows through the resistor .
This law governs the heating effect of current as heat energy released by a conductor when current passes through it. If the conductor is having resistance R and current I passes through it for time t, the heat energy dissipated, Q = I^2 X R X t.
Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat.
