Lesson

De Broglie wavelength of matter waves

Here you will learn about matter waves and how they are characterized by the de Broglie wavelength (matter wavelength).

Derivation

Capacitance - series and parallel connection of capacitors

Derive the total capacitance (equivalent capacitance) of a parallel circuit and a series circuit of two capacitors in an AC circuit.

Derivation

Self-inductance of two current-carrying wires

Derive the self-inductance and magnetic flux of two parallel current carrying conductors with opposite currents.

Question

Why are field lines always perpendicular to conducting surfaces?
