(25 cards)
Known as the motion of charge or the rate of flow of electrons/charge in a circuit.
Current
The unit for Current is named after ___
Andre-Marie Ampere
In ____, the electric field in a conductor and current is zero
electrostatics
Type of current where the direction is the same as the flow of positive charge.
Conventional Current
Current flowing per unit cross-sectional area.
Current Density
Average velocity of free charges
Drift Velocity
T/F
In drift velocity, the direction is opposite to the electric field for protons.
False (electrons siya)
T/F
The current density vectors is always in the direction of the field
True
T/F
Current due to multiple charges is the sum of all currents for each charge
True
Who introduced resistivity?
Georg Simon Ohm
Ability of a material to resist flow of current
Resistivity
Ability of a material to permit flow of current
Conductivity
Passive electrical component that provides resistance or limits the electric current in the circuit.
Resistors
Basic law of current flow named after Georg Ohm.
Ohm’s Law
Rate at which electrical energy is being used.
Power
Path of an electric current.
Electric Circuit
A ____ is a continuous path composed of conductors and devices that drives the current around.
Closed Circuit
An ____ is where the current path is not continuous.
open circuit
A ____ is a closed circuit in which a direct connection is made, with no resistance, inductance, or capacitance, between the terminals of the source of electromotive force.
Short Circuit (Imagine mo parallel connection pero walang resisotr)
The sum of voltages in a closed loop is zero.
Kirchhoff’s Voltage Law
The sum of currents entering a junction is equal to those leaving the junction.
Kirchhoff’s Current Law
A _____ is where three or more conductors meet
junction or node or branch point
A ____ is any closed conducting path
loop
Circuits with resistors and capacitors.
RC Circuit
