DC Circuits 1 Series Circuits Unit 3A series circuit provides only one path for current between two points so that
the current is the same through each series resistor. Remember, if there is
only one current path between two points, the resistors between thos two
points are in series, no matter how they appear in a diagram. - correct answer
✔Define series circuit
The total resistance is the sum of each of the individual values.
RT=R1+R2+R3+...+Rn
Also you can physically change the positions of the resistors in the circuit
without affecting the total resistance or the current. - correct answer ✔Total
Resistance
RT= 22ohm+22ohm+22ohm+22ohm+22ohm+22ohm+22ohm+22ohm =
176ohms
RT=8(22ohm)=176ohms - correct answer ✔Find the RT of eight 22 ohm's
resistors in series.
Current through any of the series resistors is the same as the total current. -
correct answer ✔Total current
If you know the total applied voltage and the total resistance, you can
determine the total current by Ohm's law. - correct answer ✔IT=Vt/Rt
If you know the voltage drop across one of the series resistor, Rx, you can
determine the total current by Ohm's law. - correct answer ✔IT=Vx/Rx
If you know the total current, you can find the voltage drop across any of the
series resistors by Ohm's law. - correct answer ✔Vx=ITRx
, The current is determined by the source voltage and the total resistance. First,
calculate the total resistance. - correct answer ✔...
if the voltage (pressure) is doubled, the current flow will doubled. - correct
answer ✔The amount of current that flows is directly proportional to the
voltage applied. Give an example...
if the resistance is doubled, the current flow will be reduced by half. - correct
answer ✔The amount of current that flows is inversely proportional to the
resistance in circuit. Give an example...
Ammeters placed at four different locations in the series circuit read the same
current value. - correct answer ✔The current that flows in a series circuit is
the same throughout the entire circuit. Give an example...
True - correct answer ✔Total current (IT) is the same value as current
flowing through any resistor in a series circuit.
True or False
inversely - correct answer ✔Current flow is ______ proportional to resistance
in a series circuit.
directly - correct answer ✔Current flow is _______ proportional to the
voltage applied in a series circuit.
True - correct answer ✔In a series circuit, the following formulas will obtain
the same value.
IT=ET/RT IT=ER1/R1
True or False
