### NCERT Solutions for Class 7 Science Chapter 14: Points to Remember

Students can note down some of the important points to remember from Class 7 Science chapter 7 as mentioned below:

• The path along which an electric current flows is known as an electric circuit.
• A closed electric circuit is an electric path which starts from the positive terminal of a cell/ battery and ends at the negative terminal without any break.
• An open electric circuit is an electric path which starts from the positive terminal of a cell/ battery but is broken at some point before reaching the negative terminal.
• Various devices/wires constitute an electric circuit.
• The galvanometer detects the flow of electric current, the voltmeter measures the potential difference, and the ammeter measures the electric current in an electric circuit.
• A combination of two or more cells is called a battery.
• An electric conductor is a material which allows electric current to flow through it.
• All metals and solutions of water-soluble acids, alkalis, and salts are good conductors of electricity.
• An electric insulator is a material which does not allow an electric current to flow through it.
• Rubber, plastic, wood, mica, paper, wax, oils, air, vacuum, etc., are bad conductors of electricity.
• Conducting wire gets hot when an electric current passes through it. This is the heating effect of the electric current.
• Nichrome is an alloy of 80%80% nickel and 20%20% chromium.
• Nichrome is used as a heating element in electric heating devices.
• The filament inside the bulb glows when current passes through it. Tungsten is used as a filament in electric bulbs.
