Study Notes
Electricity and Magnetism
- The magnitude of elementary charge is a fundamental constant of nature, denoting the charge of a proton or electron.
- If the length of a wire is doubled, its resistance will also double, given that the resistance of the original wire is R.
- The unit of Tesla is weber per square meter (Wb/m²), used to measure magnetic flux density.
- The frequency of household supply of AC in India is 50 Hz.
- The speed of electromagnetic waves is independent of the motion of the observer or the source of light.
- If the length of a wire is halved, its resistance will be reduced to half of its original value.
