Electric current is simply the flow of electric charge through a conductor.
• A cell is a source of electric current.
• Electric current is the source of all magnetic phenomena.
• Any closed path along which electric current or current carrying charge can flow is called an electric circuit.
• The heat energy produced in a conducting wire due to the flow of an electric current is known as the heating effect of an electric current.
• The amount of heat produced depends on the magnitude of the current, the time for which the current is passed, and the nature of the material of the wire.
• The electric bulb has a very thin, high-resistance filament made of Tungsten metal.
• CFL does not work on the heating effect of current. They do not have a filament and hence they do not waste electricity.
• A fuse is a safety device that prevents excessive current from flowing in a circuit. It works on the principle of the heating effect of electric current.
• The overheating of electrical wiring in any circuit due to the flow of a large current through it, (as too many electrical appliances are connected to a single socket) is called overloading of the electrical circuit.
• MCB is a special kind of an electrical switch which automatically turns off when the current in a circuit exceeds the safe limit. It works on the principle of the magnetic effect of an electric current.

Effects of electric current are as follows -
• Heating effect : When the electricity passes through a conductor,then due to the resistance of the conductor,a significant amount of heat energy is generated.
Uses : This heating effect used in filament bulbs and electrical heaters.
• Magnetic effect : When the electricity passes through a conductor,a magnetic field is generated around that conductor. This the magnetic effect of electricity.
Uses : The magnetic effect is used in the electromagnets and DC motors.
And many more.
