Direct Current

A current flowing through a conductor is said to be one ampere if 1 coulomb of charge flows through the conductor in 1 second. This note provides us an information on direct current. Learn More

Electrical Resistance

The resistance of a conductor is defined as its ability to oppose the flow of charge through it. It is measured by the ratio of the potential difference V across its ends to the current I flowing through it. This note provides us an information on electrical resistance. Learn More

Combination of Resistors and Galvanometer

Resistances are said to be connected in series when they are joined end-to-end, so that same current flows through each of them. This note provides us an information on a combination of resistance and galvanometer. Learn More

Conversion of a Galvanometer into Ammeter and Voltmeter

A galvanometer can be converted into ammeter by connecting a low resistance called shunt in parallel to the galvanometer. This note provides us an information on conversion of a galvanometer into ammeter and voltmeter. Learn More
