d2 Series, Parallel and Series-Parallel Circuits Flashcards
The voltage across all branches of a Parallel circuit is the same because ?
All branches are connected across the voltage source
You can find the total current for parallel circuit by
simply adding the individual currents. IT= I1 + I2 + I3 + ….
In a series circuit, current will be the same throughout the circuit because ?
There is only one path for current to follow
In a series circuit , the current flow will be ?
Will be the same in all parts of the circuit
To find the total resistance in a series circuit ,
just add the individual resistance : Rt = R1+ R2+ R3
If two or more resistors or consuming devices are placed one after the other
Series circuit
A single path for electrons to flow is called
A closed or complete circuit
What happens if a circuit is broken as in wire (conductor) being disconnected ?
No current would flow (open circuit)
Open circuit =
infinite circuit resistance
Circuits are?
The pathway along which electrons move to produce various effects
A short circuit means that
There is a path of low or lower resistance to electron flow that is frequently unintended or accidental
Fuses are placed in
In series with the consuming devices
Fuses are used to prevent
the damaged done by excess current flowing in a circuit
Ground
zero voltage point of the system
Earth Ground
where all of the wiring grounds are connected to. Is used to guide electrical current away from panels and equipment.
Chassis
the frame of the equipment where the ground wire in an electrical cord us connected to.
A Short circuit Is something to be avoided because it can
It can cause a fire or overheating
A loose connection can cause
An Open circuit
The total resistance (RT) of a parallel circuit cannot be found
by adding the resistors values
Instead use the 2nd function x-1 calc values do the same to the answer
Current in a parallel circuit depends on ?
The resistance of the branch
A load resistance is inversely proportional to current because ?
If a loads resistance were to decrease , the current flowing in the circuit would increase
Power is defined as
The rate at which work is done
P = I x E
Total power consumed in the circuit is equal to the
sum of the individual power consumptions (PT = Pl + P2 + P3… + PN).
Any complex combination circuit can be reduced to
an equivalent resistance or simple circuit.
After the total resistance of a combination circuit is reduced to a simple series or parallel circuit, the source voltage
can be applied and the total current value determined.
Kirchhoff’s current law states that the total current entering a junction or parallel circuit is
equal to the current leaving that junction or parallel circuit.
In a parallel circuit, the voltage is
equal through the circuit ((ET = El = E2 = E3… = EN).
The total resistance in a series circuit is equal to
The sum of all the resistance values in the circuit (RT = Rl + R2 + R3… + RN).
The source voltage in a series circuit is equal to
the sum of the voltage drops (ET = El + E2 + E3… + EN).
The device used to produce electricity by heat is the
Thermocouple
