All Flashcards
What is the effect of moving closer to a positive charge?
The electric potential increases.
What happens when a positive charge moves from a region of low potential to high potential?
The electric potential energy of the charge increases, requiring work to be done.
What happens when a positive charge moves from a region of high potential to low potential?
The electric potential energy of the charge decreases, and work is done by the electric field.
What is the effect of increasing the distance from a charge on the electric potential?
The electric potential decreases as distance increases, according to $V = \frac{kQ}{r}$.
What is the relationship between electric field lines and equipotential lines?
Electric field lines are always perpendicular to equipotential lines.
What is an isoline?
A line connecting points of equal value in a scalar field.
What are equipotential lines?
Isolines that connect points with the same electric potential.
Define electric potential (V).
The potential energy of a charged particle in an electric field, measured in volts (V).
Define voltage (ฮV).
The difference in electric potential between two points, measured in volts (V).
What is the formula relating voltage, work, and charge?
$V = \frac{W}{q}$, where V is voltage, W is work, and q is the charge.
What are the key differences between electric potential energy and electric potential?
Electric potential energy (U or W) is measured in Joules. Electric potential (V) is measured in Volts and is a scalar quantity.
Compare equipotential lines in uniform vs. non-uniform electric fields.
Uniform field: Equipotential lines are evenly spaced and parallel. Non-uniform field: Equipotential lines are curved, indicating varying field strength.
