Atom: Atom is nothing but a smallest tiny particle of a chemical element,it can't be divisible further is called as Atom
Nucleus : A nucleus is the positively charged center of the atom consisting if proton and neutrons is called nucleus
- Electron: A negatively charged particle is nothing but electron
- Electron is discovered by JJ Thomson (1897)
- Charge electron is -1.6*10^-19 eV
- Proton : A Positively charged particle is nothing but proton it has same magnitude of electron charge 1.6*10^-19eV
- Neutron : There is no charge on the Particle
Voltage: The Potential difference between the two ends of the conductor is called Voltage (Units are Volts (V))
Current : The time taken by the charge to posses through the cross sectional area of a conductor is called as Current
- Current is indicated with i
- Units of Ampere
Power : The Product of voltage and current is nothing but Power
- P=VI (Volt-Ampere (Watts))
- Power indicated with P
Conductor : The Conductor is a material it allow the electricity is nothing but Conductor.
Examples: Cu, Fe, Al
Insulator : It doesn't allow the electricity is called insulator
Examples: wood
Semiconductor : It is a semi Conductor some times it acts has a insulator and some times a ts as a Conductor based on the requirement is called semiconductor
Examples : Si, Ge
