If we take output across 𝑅c in a CE amplifier instead of across collector and emitter or (ground). Would it blow up my circuit?
A common emitter transistor is usually part of a larger circuit, and the rest of the circuit will usually expect signals to be relative to ground. If you have only a single CE transistor then yes you ...

Driven $RLC$ circuit why is the permanent signal sinusoidal and why two degrees of freedom (amplitude and phase)?
that the particular solution (i.e. the permanent signal) is also sinusoidal, with the same periodicity as the RHS term function?
Answer 1: Because the system is linear.
Answer 2: Can you find another ...

Why aren't brightness and loudness represented as spectra?
They can be.
In many applications, people just want to know about or control the overall amplitude of a signal (think turning the lights or the radio up or down), and don't care to know or control ...

Why aren't brightness and loudness represented as spectra?
The problem is terminological - Brightness is a subjective characteristic of human light perception, not a physical quantity.
Light intensity is more physical term, but it may mean many different ...
