Electric Circuits
In an LRC series circuit where L is negligible, how does quadrupling only the dielectric strength between capacitor plates affect resonant frequency assuming physical dimensions stay identical?
Resonant frequency doubles as higher dielectric strength indicates stronger electric fields that lead to quicker discharge cycles through resistor-capacitor sequence.
Resonant frequency halves because enhanced dielectric strength implies more energy storage capability thereby reducing natural oscillation rate.
Resonant frequency reduces to one fourth given that stronger dielectrics produce greater impedance against changing fields thus slowing resonances down markedly.
Resonant frequency remains unaffected as dielectric strength alteration impacts breakdown voltage not stored charge nor oscillation dynamics governing resonance.
If the distance between two parallel plate capacitors is doubled while keeping all other factors constant, what happens to the capacitance?
It quadruples.
It is halved.
It doubles.
It remains unchanged.
What outcome can be expected if magnetic permeability throughout the universe unexpectedly dropped tenfold altering self-inductance coefficient affecting circuits containing non-negligible L components?
Longer time constants reflecting heightened opposition to flux changes, hence slower circuit reactions.
Increased power dissipation per cycle attributed to losses stemming from intensified interaction between magnetic fields components.
No significant effect observable outside superconductive regimes where magnetic effects predominate over electrical ones.
Reduced overall circuit impedance, consequently shorter transient response periods upon switching states or signals.
What happens to the resistance of a conductor when its temperature is increased?
It decreases.
It increases.
It becomes zero.
It remains constant.
What best describes enthalpy (H) in terms of its components?
The sum total kinetic energies all atoms within system calculated per degree freedom each molecule possesses.
It's a measure of total energy including internal energy plus product of pressure and volume.
What device is typically used to store electric charge in a circuit?
Inductor
Diode
Resistor
Capacitor
