190104b electrical circuits Flashcards
minimal electric circuit component
- power source
- conductor
- load
- control
types of circuits
- series
- parallel
- series parallel
identification character of a series circuit
- current is always constant
- only one flow for current
- the current is the same at every point
- the resistance of the circuit is equal to all the single resisters
- the sum of voltage drop across each resistance equals the applied voltage
name all the parallel identifying charactorristics
- voltage is always constant
- current flow thru each path is dependant on the resisters and voltage applied to each path
- total current flow is equal to the sum of the current from each path
- adding resistances in a parallel decrease total resistance ( more paths)
- removing resistance increase resistance (fewer paths)
- total resistance will always be less then the smallest resistance in a circuit
in a parallel, voltage to each branch would be
the same (pressure is applied equally)
what does ohm’s law states
one volt is needed to force one ampere of current to flow through one ohm of resistace
E stands for
I stands for
R stands for
electromotive force
intensity of current flow
resistance to current flow
whats kirchhoff’s current law
the sum of the electrical current flowing away from any point in an electric circuit must equal the sum of the currents flowing towards the point
whats kirchhoff’s voltage law
law states that around any path in an electric circuit, the sum of the voltage drops is equal to the sum of the voltage rises.
