2025/2026- 100+ QUESTIONS AND VERIFIED ANSWERS 100%
CORRECT GUARANTEED SUCCESS
Lab 1 Electrostatic Forces: Why was it not possible to repeat your measurements?
there was no way to quantify the charge and the rod was constantly losing charge
Lab 1 Electrostatic Forces: systematic error
Consistently using different pressure or speed when rubbing the rods with
materials.
Lab 1 Electrostatic Forces: random error
Inconsistencies in measuring the distance between the rod and the pith ball due
to accidental movements of the setup that also affected the pith ball's position or
charge leakage over time due to contact with surfaces or exposure to the air.
Lab 2 Capacitance: Testable Questions
A) How is the capacitance of a parallel plate capacitor related to the distance
between plates?
B) How is the capacitance of a parallel plate capacitor related to the overlapping
area?
Lab 2 Capacitance: Hypotheses
A) If the distance between plates is increased, then the capacitance will decrease
because there is less electric field force between the plates as they get further
apart.
B) If the overlapping area is increased, then the capacitance will increase because
there is a larger area for the electric field.
Lab 2 Capacitance: Controls
, 2
A) overlapping area (A), dielectric constant (k), permittivity constant (E0)
B) distance between plates (d), dielectric constant (k), permittivity constant (E0)
Lab 2 Capacitance: IV and DV
IV: A) distance between plates B) overlapping area
DV: capacitance
Lab 2 Capacitance: Why did you put a textbook on top of the capacitor?
didn't want any air particles in between the plates
Lab 2 Capacitance: Systematic error
A) Not aligning the plates correctly (in the same or similar way) each round could
create inconsistencies in the electric field therefore leading to a lower measured
capacitance.
B) Uneven distribution of charge among the plates because of an imperfect
surface.
Lab 2 Capacitance: Random error
A) Inconsistencies with the capacitance meter as it was not very consistent and
would often change values drastically, leading to non-precise data.
B) Inconsistency in the positioning of the plates such as misaligning the capacitor
plates. If the plates move slightly, the effective area could be different from the
measured values, impacting the readings and leading to errors.
Lab 3 Resistance of a Wire: Testable Question
How is the resistance if a wire related to the length of the wire?
Lab 3 Resistance of a Wire: Hypothesis
If the length of the wire increases, the resistance in the wire will increase because
the electrons must travel further resulting in more electron friction.
