Who found heating effect of electric current?
The heating effect of electric current was discovered by James Prescott Joule in the mid-19th century. Joule's experiments showed that the temperature of a conductor increases when an electric current passes through it.
What causes heating in wire?
Heating in wire is caused by the flow of current through the wire. The resistance in the wire causes energy to be converted into heat as the electrons move. This heating effect is known as Joule heating.
Why does heating effect of electric current happen?
When an electric current flows through a conductor, the electrons collide with atoms in the material, transferring energy in the form of heat due to resistance. This resistance causes the material to heat up, a phenomenon known as Joule heating. The heating effect is a result of the conversion of electrical energy into thermal energy.
How do you derive joule's law?
Joule's law, which states the relationship between electrical power, current, and resistance, is derived from Ohm's law, P = IV, and the formula for electrical power, P = I^2R. By substituting I = V/R from Ohm's law into the power formula, you can derive Joule's law as P = V^2/R.
What term describes the cooling of a gas by expansion?

What kitchen appliance makes use of the Joule-Thompson effect?
A refrigerator is a kitchen appliance that makes use of the Joule-Thompson effect to cool food and beverages stored inside.
How does a heating pad work?
Heating pads contain heating elements that convert electricity to heat by passing current through a conductor (usually a wire). This process is variously referred to as resistive heating, ohmic heating, or Joule heating. The amount of heat generated is proportional to the square of the applied current multiplied by the resistance of the conductor. If SI units are employed (amperes for current and ohms for resistance) the unit of heat energyis called a joule.

What heats the wire of a light bulb?
When electricity passes through the wire of a light bulb, the resistance in the wire causes it to heat up through a process called Joule heating. This heating effect causes the wire to reach such high temperatures that it emits light and produces illumination in the bulb.
What term describes the cooling of a gas by expansion?
Joule-Thomson effect.
How is the Joule-Thomson effect calculated in thermodynamics?
The Joule-Thomson effect is calculated in thermodynamics by using the Joule-Thomson coefficient, which is the rate of change of temperature with pressure at constant enthalpy. This coefficient is determined by taking the partial derivative of temperature with respect to pressure at constant enthalpy. The formula for the Joule-Thomson coefficient is given by (T/P)H, where is the Joule-Thomson coefficient, T is temperature, P is pressure, and H is enthalpy.
