Electricity

We know that when temperature and other physical conditions (e.g. – length, cross-section, area) remain the same, the resistance of a conductor is a constant.…

The electricity flows through a conductor due to the potential difference between the two terminals. The potential difference between any two points is defined as…

Electrical energy is needed to produce the electric current in a circuit. The electromotive force of an electrical energy source is defined as the work…

A resistor is a conductor used in a circuit that has a known value of resistance. Resistors come under passive electronic components and are extensively…

We know electric current is the flow of electrons. When the electrons move within the bulk of a conductor, they collide with the atoms and…

We know, if there is a potential difference between the two terminals of a conductor, current flows through it. The quantity of this electric current…

The current passing through a conductor at constant temperature is directly proportional to the potential difference between the two ends of the conductor. By proportionality…

We know, the electric current is the flow of charges through a material. This electric current can move very easily through some substance. There are…

The complete path through which electric current can flow is called electric circuit. When two plates of a cell are joined to the two ends…

When current electricity was invented first, it was assumed that the electricity was produced due to the flow of positive charges. This positive charge flows…
