Coulomb's Law
- Two stationary point charges q1 and 12 repel or attract each other with force F which is directly proportional to the product of the charges and inversely proportional to the square of the distance r between them. F ∝ q1q2 F ∝ 1/r^2 F = a q1q2/r^2 a = 1/4πe0 a = 9.0x10^9 Nm^2C^-2
Electrification
- for the electrification of a body only electrons are responsible
- Conductors
- The substances in which electric charge can flow are called Conductors ... Higher the flow of charge good is the conductor.
- Semiconductors
- These are the substance which regarding their electrical conductivity are intermediate between
- Insulators
- The substance in which electric charge cannot flow is called Insulators(or dielectric). The less the flow of charge, the good insulator will be .
Charge
- Types of Charges
- Positive
- +ve +ve repels whereas +ve -ve attracts
- Negative
- -ve -ve repels whereas -ve +ve attracts
- Positive
- Units
- SI Unit : coulomb electric current = charge/time charge = electric current x time 1 C = 1 A . 1s 1 C = 1 A-s 1 ampere is the current, which when flows in each of the two inifinite long parallel conductors 1 meters apart produces a force of 2x10^-7 N/M between them. If a conductor carries a current of 1 ampere for 1 second, then the charge flown through that conductor will be 1 coulomb.
