Electric Force, Field, and Potential
What type of energy conversion occurs in a photocell (solar cell) when light shines on it?
Heat to electric energy via thermionic emission due to light absorption raising temperature.
Chemical to electrical energy via photosynthesis-like reactions driven by light exposure.
Mechanical to electric energy via piezoelectric effect induced by photon pressure.
Electromagnetic radiation to electric energy via the photoelectric effect.
What does Ohm's Law state about the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit?
V = I/R because the voltage equals current divided by resistance.
V = IR because voltage is equal to the product of current and resistance.
R = VI because resistance is the product of voltage and current.
I = VR because current equals dividing voltage by resistance.
In which scenario would an alpha particle (a helium nucleus) experience no net force while moving in combined electric and magnetic fields?
When it travels at any angle as long as both fields have equal strength.
When it travels parallel to both fields if they are also parallel to each other.
When it travels perpendicular to the electric field and parallel to the magnetic field.
When it travels perpendicular to both fields if they are parallel.
In an ideal capacitor that has been fully charged, where is the energy stored?
Within the dielectric material only
In the chemical bonds of capacitor materials
In the electric field between the plates
At one specific plate, either positive or negative
How does the electric potential energy change when two like-charged particles are moved farther apart?
It remains constant because electrical forces are conservative.
It decreases because work is done by the electrostatic force.
It becomes zero as the particles are separated infinitely far apart.
It increases because work is done against the electrostatic force.
Which condition would result in maximal transferal rates between internal stored chemical power sources converted into retained static electricity across capacitive elements given circuitry containing only reactance-free components?
Activating bi-directional semiconductor junctions promote extensive carrier mobilizations which enhance local electrifications concomitantly preserving overall energetic equilibriums.
Transference efficiency peaks when reactive impedance summations approach nullification thresholds permitting uninhibited direct current flow throughout.
Harmonic oscillatory inductions maximize cross-sectional dielectric polarizations henceforth optimizing static retention capacities despite systemic resistances.
Incremental resistance additions cause insignificant dissipative heating effects thereby elevating static charging efficiencies notwithstanding alternative pathway options.
What happens to an ideal capacitor's stored electrical potential when its capacitance decreases while maintaining a constant charge?
The voltage remains constant as it depends solely on battery voltage which hasn't changed.
The voltage across it increases due to relation where is constant and decreases.
No definitive conclusion can be drawn without knowing how the dielectric material was altered to reduce capacitance.
The voltage decreases because reduced capacitance implies lower storage capability for charge at any given voltage level.
