define law of joule odefine law joule of heating
Answers
Answer:
Joule's laws are two: first about heat produced by an electric current, and second about how the energy of a gas relates to pressure, volume and temperature. Joule's first law shows the relation between heat generated by an electric current flowing through a conductor.
hi mate,
we know that the One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter.
One joule is the equivalent of one watt of power radiated or dissipated for one second. In some applications, the British thermal unit (Btu) is used to express energy.
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.
i hope it helps you.
