(15 cards)
Region in space where points in the electric field have equal potential, represented by lines surrounding the point charge
equipotential surface
This concept is crucial in understanding electric fields and potentials.
an energy due to a moving charge changing displacement within a projected electric field provided by a rest charge
Electric potential energy
It reflects the work done to move a charge against an electric field.
Electric Potential is also known as?
Voltage
Electric potential energy per unit charge, measured in volts (V).
Difference between two electric potential values, responsible for generating electric current
potential difference
Earth’s Potential is defined as zero.
Energy transfer between electric charges influenced by a rest charge
electric work
It is also affected by the electric force within a certain radius.
Local rate of change of a potential with respect to displacement
potential gradient
Positive charges are accelerated down gradients, while negative charges are accelerated up gradients.
An electric component that stores electrical energy within an electric field, found between its plates
capacitor
Plates are separated by vacuum or an insulator.
Ability of a capacitor to store charge, changing the voltage of a body by one unit
capacitance
Measured in farads (F).
factors affecting Capacitance.
- Area of the plates
- Distance separating the plates
- Nature of insulating materials
- Uniform electric field within the plates’ space
These factors influence how much charge a capacitor can hold.
Energy stored due to half the work performed
stored energy in capacitors
This energy can be calculated based on charge and voltage.
Insulating material inserted between a capacitor’s parallel plates, increasing capacitance
dielectric
It does not compromise the capacitor’s separation distance.
total capacitors within given sets of capacitors
equivalent capacitance
Represents the capacitance of all capacitors combined.
Connected devices in a single fashion, sharing charge values
series circuit
This affects the total resistance and voltage in the circuit.
Connected devices are independent from each other, sharing voltage values
parallel circuit
This allows for multiple paths for current flow.
vacuum permittivity
