Chemical Effect of Electric Current. When an electric current passes through a solution, the solution ionizes and breaks down into ions. This is because a chemical reaction takes place when an electric current passes through the solution. Depending on the nature of the solution and the electrodes used, the following effects can be observed in ...
Effects of Electric Current. You performed many experiments with electricity in Class 6 and learned quite a few interesting facts. For example, you saw that a bulb can be made to light up by making electricity flow through it. The light of the bulb is thus one of the effects of electricity. There are several other important effects of electricity.
Two effects of electric current are: Electromagnetic effect Heating effect Electromagnetic Effect: The magnetic effect of electric current is known as electromagnetic effect. One can easily observe this phenomenon by bringing near a current carrying conductor to a compass needle. When the current carrying wire is brought close to the magnet it ...
14.2 Heating Effect of Electric Current. 14.3 Magnetic Effect of Electric Current. 14.4 Electromagnet. 14.5 Electric Bell Key Points discussed in the Chapter-An electric circuit is represented by a circuit diagram as representing electric components by symbols is the most convenient way of studying them.
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.
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
Electric furnaces, for instance, rely on the heating effect to achieve high temperatures for metalworking and chemical production. Magnetic Effects. When electric current flows through a conductor, it generates a magnetic field around it. This effect forms the basis of many technologies, from electric motors and generators to transformers and ...
Effects of Electric Current:-There are three main phenomena that an electric current can produce.They are: (1) Heating effect – When an electric potential is applied to a wire the drift of electrons is opposed by the resistance of the wire, so heat is produced. The production of electrical heat can well be compared with the production of mechanical heat with motion against frictional resistance.
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 ...
Types of Electric Current. Electric current is categorized into two main types based on its flow direction and behavior over time:. 1. Direct Current (DC) Definition: Direct Current (DC) flows in one constant direction without changing over time.. Electron Movement: Free electrons move from the negative terminal to the positive terminal in a DC circuit.
• Lighting effect of electric current is used in bulbs, fluorescent tubes. • Compact fluorescent lights are a modification of fluorescent tubes which emit more light with less of electric energy consumed. Magnetic Effect: Magnetic effect of electricity is of great use in our day to day life, in industries, in the field of medicine etc.,
Here, I is the current and t is the time. 2) Magnetic effect of electric current: We know that when the current passes through a conductor, the magnetic field produces along with it a circular path around the conductor. The direction of the magnetic field can be determined using Right-hand thumb rule. Note:Students can also state the effect of ...
What are the effects of electric current? An electric current can have various effects. Some of these include: Heat: a product of the conductor’s temperature increase due to the flow of the electric current. One example of this is a stove. Magnetic: when an electric current passes through a conductor, it creates a magnetic field around it ...
Effects of electric current. When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects. 1. Heating effect. When the flow of current is ‘resisted’ generally heat is produced. is is because the electrons while moving in the wire or resistor su er resistance.
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.
1. How does electric current cause a heating effect in a conductor? When electric current flows through a conductor, the free-moving electrons collide with the atoms in the conductor. This collision generates heat due to the resistance offered by the conductor to the flow of current, known as the heating effect. 2.
1. When electric current flows through a wire, the wire gets heated. It is the heating effect of current or when current flows through a metal wire it gets heated up, this is called the heating effect of current. E.g. a glowing electric bulb becomes warm. This effect has many applications like Electric Heater, Light Bulb etc. 2.
Additionally, understanding the effects of electric current highlights the importance of safety measures. 1.0 Download CBSE Notes for Class 7 Science Chapter 10: Electric Current and Its Effects - Free PDF. Dive into the fascinating world of electric current and its effects with these concise notes of Class 7 Science. This chapter illuminates ...
