Write down the law of length for resistance. At constant temperature, if the cross-sectional area of a conductor is kept constant then the resistance of that conductor is proportional to the length of that conductor.
What is used to make the filament of an electric bulb? Tungsten.
What is the connection of resistors? Joining of two or more resistors is called a connection of resistors.
What is electric energy? If a voltage is applied on both sides of a conductor current flow takes place through that conductor. The energy gained by the electrons due to this conduction is called electric energy.
What is semiconductor? The materials having conductivity lower than conductors and higher than insulators are known as semiconductors.
What is the flow of charge through a conductor? The flow of charge through a conductor is known as electricity flow.
What is the SI unit of electromotive force? SI unit of electromotive force is volt.
Write down Ohm’s law. At a constant temperature, the current flowing through a conductor is proportional to the potential difference of that conductor.
