circuitsElectric current - correct answer ✔The FLOW of electrons through a
conductor
Direct current - correct answer ✔Electrons made to flow in one direction only
along the conductor.
Direct current is a waveform diagram as: - correct answer ✔a straight line
------------------------
Alternating current (AC) - correct answer ✔Current in which electrons
oscillate back and forth.
-flow in a positive direction then a negative direction.
Alternating current is a waveform diagram as: - correct answer ✔a sine curve
Once they reach maximum flow the electric potential is reduced , return to
zero and reverse motion. is an example of? - correct answer ✔Alternating
current (AC)
Series Circuit - correct answer ✔A circuit in which the current has only one
path to travel
-connected end to end
A break anywhere in the path results in an open circuit and the flow of
electrons ceases. - correct answer ✔A series circuit
, Total resistance is - correct answer ✔Equal to the sum of the individual
resistances along the circuit path.
RT= R1+R2+R3 Is what? (series circuit) - correct answer ✔(Total resistance)
is equal to the sum of the individual resistances along the circuit path.
IT=i1=i2=i3 is what? (series circuit) - correct answer ✔(Current) through each
circuit is equal to the total circuit current.
VT=V1+V2+V3 Is what? (series circuit) - correct answer ✔The sum of the
voltages across each resistor is equal to the total circuit voltage.
There are two types of circuits what are they? - correct answer ✔Series and
Parallel
Parallel circuit - correct answer ✔A circuit in which there is more than one
path for the current to flow.
A break in any one path does not interrupt the flow of charge in other paths is
an example of? - correct answer ✔Parallel circuit
-each device operates independently of the other devices connected to the
circuit.
IT=i1+i2+i3 is what? (parallel circuit) - correct answer ✔sum of the current
through each circuit element is equal to total circuit current.
VT=V1=V2=V3 Is what? (parallel circuit) - correct answer ✔voltage across
each circuit element is the same and is equal to the total circuit voltage.
