Class 10 Science Chapter 12 Electricity: Important Topics
Electricity is a type of energy that may be witnessed in both positive and negative forms, either naturally as lightning or manufactured artificially as a generator. When a stream of charged particles such as ions moves across space, this is referred to as an electric current. The standard unit of electric current is the ampere. It is defined as a charge flow rate of one coulomb per second. It is calculated as 6.2 1018 electrons per second in numerical terms.
1 ampere = 3 x 109 esu per second
esu is an abbreviation for the electrostatic unit of charge.
C stands for Coulomb.

Ohm’s Law
Ohm’s law states that the resistance, or the ratio of voltage to current, for all or part of an electric circuit at a fixed temperature, is generally constant. Ohm's law may be expressed mathematically as V/I = R. The law had been established by 1827 as a result of the investigations of the German physicist Georg Simon Ohm.

Resistance
Resistance can be defined as a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, which is symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm, a German physicist who studied the relationship between voltage, current, and resistance.
