Joule’s Law – Joule Effect or Heating Effect of Current and its Applications. An English physicist James Prescott Joule discovered the Joules’ law (also known as Joel’s effect, Joule-Lenz law or Joule’s first law) in 1840-43 which shows the relation between current, heat and resistance in a specific time i.e. when a current flows through a material, it produces heat in it.
5.0 Heating effect of electric current. We know that to maintain the current, the source (cell or battery) has to keep expending its energy. A part of the source energy is consumed into useful work like in rotating the blades of an electric fan, producing light and sound in television, etc. Rest of the source energy is converted to heat to ...
We make use of these Effects of Electric Current in various electrical appliances. When the current flows through a circuit various effects of current happen depending on the components being used. (a) heating effect of electric current (b) magnetic effect of electric current (c) chemical effect of electric current
Magnetic Effect of Electric Current. Electric Current produces a magnetic force which can likewise be named the magnetic effect. The magnetic impact of electric current is known as electromagnetic impact. When a compass is brought close to a conveyor, the needle gets redirected in direction of the flow of electricity.
Here are some home appliances that use the heating effect of the current: Electric kettle; Electric stove; Electric oven; Toaster; Water Heater; Clothes ironing; Bulbs; Electricity and Magnetism (Magnetic Effect) The next effect of the electric current is magnetism. In 1819, Hans Christian Oersted discovered that electricity has a magnetic effect.

Learn about the heating, chemical and magnetic effects of electric current with examples and diagrams. Find out how Joule heating, electrolysis and Oersted's experiment work.
So, the electric fuse uses the heating effect of current to keep electrical circuits safe by breaking the circuit when there's too much current flowing through it. Chemical Effect. a) Electric current can cause chemical changes in certain substances. This is called the chemical effect of electric current or electrolysis.
Effects of Electric current. There are mainly two effects of electric current: Heat effect: Current is dissipated in the form of heat. Heat evolved is directly proportional to the current flowing. If the current flowing is less, heat will be less and if the current flowing is more, more amount of heat is produced.
Magnetic Effect of Electric Current. When current flows through a wire, it creates a magnetic field. This can be observed by the deflection of a compass needle placed near the wire. Winding the wire into a coil enhances this effect, creating an electromagnet, which is useful in various applications. 3. Chemical Effect of Electric Current
The chemical effect of electric current finds numerous applications in various fields, contributing to advancements in technology, industry, and research. Electroplating. One notable application of the chemical effect of electric current is electroplating. Electroplating is the process of applying a slim metal coating onto a surface by means of ...
