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.

Why doctors use concave mirror to observe eyes, ear, nose, throat? We know, incident rays on a concave mirror can create convergent rays. With the help of this mirror, the rays can be accumulated in a single point. As a result, a magnified image of the object can be seen if it is placed within … Read more
