What is the effect of increasing resistance in a circuit with constant voltage?
The current decreases (Ohm's Law).
What happens when a dielectric material is inserted into a capacitor?
The capacitance increases, allowing it to store more energy.
What is the definition of Electric Current?
Flow of electric charge (measured in Amperes, A).
What is the definition of Voltage?
Electric potential difference (measured in Volts, V).
What is the definition of Resistance?
Opposition to current flow (measured in Ohms, Ω).
What is a Capacitor?
A device that stores energy in an electric field.
What is an Inductor?
A device that stores energy in a magnetic field.
What is Electric Flux?
Measure of electric field through a surface.
What happens when the separation distance between capacitor plates decreases?
The capacitance increases, and the energy stored in the capacitor increases if the voltage is kept constant.
What happens when a dielectric material is inserted between the plates of a capacitor?
The capacitance increases.
What happens when the resistance in a circuit increases, assuming voltage remains constant?
The current decreases, according to Ohm's Law (V = IR).
