Who found heating effect of electric current?
Joule showed the heating effect due to the resistence of wire which cary the current.
How do you derive joule's law?
State and derive joul's law of heating effect of an electric current.
How does electricity produce heat and light?
it is due to joule heating effect .whenever the current passes through a metal it produces heat.this principle is used ina controlled way in many of the heating devices like electric iron,water heater etc.
State the situations where heating effect of electric current is undesirable?
negative effect of science .. with picture
What are the advantage and disadvantages of heating effect of current?
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.

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 are the applications of joule Thomson effect?
two application joule thomson 1. linde methode 2. liquiefied
Joule Thomson effect is temperature dependent or not?
its temperature dependent
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.
How would you show the heating effect of a current?
how would you show the heating effect of a current?
Is joules heating always desirable?
Joule heating is referred to as ohmic heating or resistive heating because of its relationship to Ohm's Law. It forms the basis for the myriad of practical applications involving electric heating. However, in applications where heating is an unwanted by-product of current use (e.g., load losses in electrical Transformers) the diversion of energy is often referred to as resistive loss. The use of high voltages in electric power transmission systems is specifically designed to reduce such losses in cabling by operating with commensurately lower currents. The ring circuits, or ring mains, used in UK homes are another example, where power is delivered to outlets at lower currents, thus reducing Joule heating in the wires. Joule heating does not occur in superconducting materials, as these materials have zero electrical resistance in the superconducting state. so it is sometimes desirable and sometimes not............
Science fair do heating and cooling effect the strength of glass?
No, heating and cooling does not effect the strength of a glass
