Ch 2 Flashcards
What are the 6 ways DC voltages are produced?
Chemical - Battery aka electrochemistry
Heat - thermocouples aka thermoelectricity
Light - photocell or solar cell aka photoelectric effect
Magnetism - Generator - aka magnetic induction
Friction - Static or lightning aka static electricity
Pressure - Piezoelectric
What converts AC to DC?
Rectifier
Has a complete path for current flow.
Closed Circuit
Does not have a complete path for current flow.
Open Circuit
Circuit with a path that has little resistance to current flow.
Short Circuit
One path for current flow.
Series Circuit
Has two or more components connected across same voltage source.
Parallel Circuit
Used to obtain different values of voltage from a single energy source.
Voltage Divider
Where the electron current enters the load, the voltage is…
Negative
What will result in no power being consumed by any loads?
Open series DC Circuit
The effect of an opening in a parallel circuit is dependent upon what?
Location of the open in the circuit.
Shorted DC Circuit will result in what?
Sudden and large increase in Circuit current
Sum of the voltage drops around a closed loop is equal to the sum of the voltage sources around that loop.
Kirchhoffs Voltage Law
Current arriving at any junction pt in a circuit is equal to the current leaving that junction.
Kirchhoffs Current Law
Voltage and current can be related to energy and potential.
Kirchhoffs laws only restate laws governing energy and charge conservation.
