Combination of two or more cells in series is called
Combination of two or more cell in series is called battery.
Which of the following is bad conductor of electric current?
Diamond is an extremely bad conductor of electricity. In diamond, each carbon atom is covalently bonded with four other carbon atoms. So, the four outermost electrons of a carbon atom are engaged or trapped in the covalent bonds, having no free electrons making it a bad conductor of electricity.
Filament of electric bulb is made up of
Filament of electric bulb is made up of tungsten due to high resistivity and high melting point.
In which case bulb will glow if following materials are placed in circuit?
Only metal spoon will allow the current to pass through because all others are insulators.
The materials that have high resistance are called
These are the materials which offers very high resistance to the flow(or in path) of electric Current.
In other words these materials have very high resistivity.
A thin coil of metal, which glows when electricity is passed through it, is called
A thin coil of metal, which glows when electricity is passes though it is called filament.
Which one of the following will allow electric current to pass through?
Iron nail being a metal is a conductor of electricity while the rest are insulators.
Closed and continuous path of electric current is called
Closed and continuous path of electric current is called circuit.
