Basic circuit theory of operation Flashcards
what is the SI base unit of electrical current
ampere
what contains four impedances that form a square
bridge connects
what are international measure of energy expended in the kilogram, meter, and second system of units
joules
what contains a combination of series and parallel circuits
complex circuits
what is Kirchhoff’s current law (KRL)
Kirchhoff’s Current Law states that “the algebraic sum of the current flowing away from any point in an electrical circuit is equal to the sum of the current flowing to that point”
what is Kirchhoff’s resistance law
Kirchhoff’s Resistance Law states that “the total resistance in a series circuit is
the sum of the individual resistances or loads in the circuit”
what is Kirchhoff’s voltage law
Kirchhoff’s Voltage Law states that “the algebraic sum of all of the voltage drops
in any closed circuit is equal to zero”
what is the law that states that electric current is proportional to voltage and inversely proportional to resistance
ohms law
what contains more than one path for current
parallel circuits
what is the product of applied voltage and current power in a dc circuit
power
what is is a measure of the opposition to current flow in an electrical circuit
resistance
what causes a reduction of current in multiple circuits
resistors in parallel circuits
what causes a reduction of current in one circuit
resistors in a series circuit
what contains only one path for current making current common through all components
series circuits
what is reduction in voltage caused by current flowing through a resistor
voltage drop
