Study Notes
Electric Charge and Current
- The SI unit of electric charge is the coulomb (C).
Scalar Quantities
- An example of a scalar quantity is electric charge.
Waves
- The frequency and wavelength of a wave are inversely proportional, meaning that as the frequency increases, the wavelength decreases, and vice versa.
Electricity
- The SI unit of electric current is the ampere (A).
- The relationship between voltage, current, and resistance in a circuit is described by Ohm's Law: voltage = current × resistance (V = I × R).
Test your knowledge of Class 12 Physics with these important questions. Challenge yourself with topics including SI units, scalar quantities, and the relationship between frequency and wavelength of a wave.
