Chapter 13 Flashcards
Circuit
A closed loop or pathway through which electric current can flow
Electric Current
The flow of electric charge through a conductor
Ohm’s Law
States that the voltage across a conductor between two points is directly proportional to the current flowing through the conductor, provided that the temperature remains constant
Resistance
A fundamental property of a material or component in an electrical circuit that impedes the flow of electric current
Conductivity
A measure of how well a material conducts electric current
Electromotive Force
The energy per unit charge provided by a source (such as a battery or generator) to drive electric current through a circuit
Series Circuit
A type of electrical circuit in which the components are connected end-to-end, forming a single path for current flow
Parallel Circuit
A type of electrical circuit in which the components are connected across common points, forming multiple paths for current flow
Direct Current
An electrical current that flows continuously in one direction through a conductor
Alternating Current
An electrical current that periodically changes direction, reversing its flow at regular intervals
Effective Current
The equivalent steady direct current (DC) that would produce the same amount of power dissipation in a resistive load as the AC current
Effective Voltage
The equivalent steady direct current voltage (DC) that would produce the same amount of power dissipation in a resistive load as the AC voltage
Sinusoidal (sine) Curve
A smooth, periodic waveform that oscillates above and below a central axis
