Chapter 5 multiple- load circuitsSubscripts - correct answer ✔Are used to identify the different-load resistors
in the circuit.
Total resistance - correct answer ✔In a series circuit is equal to the sum of
the individual resistances around the series circuit.
Series circuit - correct answer ✔Contains two or more loads but only one
path for current to flow from the source voltage through the loads and back to
the source.
One path for current - correct answer ✔Any part of the circuit can be
interrupted to insert the meter.
Kitchen hoff's voltage law - correct answer ✔The sum of the voltage drops
around a circuit equals the applied voltage
Voltage drop - correct answer ✔The voltage, or potential energy difference,
across a resistor.
Polarity - correct answer ✔It indicates the direction of current flow and the
conversion of electric energy to another form of energy.
Open - correct answer ✔Current stops flowing and voltage and power are
removed from all loads.
, Shorted out - correct answer ✔The other loads may continue to operate. Or
one of the other loads may open because of increased voltage,current, and
power.
Using subscripts - correct answer ✔Use to identify the different load resistor
in the circuit
Voltage-divider equation - correct answer ✔Vrn=VtRn/Rt
Cross check - correct answer ✔This can usually be done by checking some
relationship not used in originally solving the problem
Estimate - correct answer ✔When estimating current in a series circuit,
ignore the lowest resistance if it is less than the tolerance of the highest
resistance
Motor- speed control - correct answer ✔This type of control is used in very
small motors, such as a motor on a sewing machine.
Variable resistor - correct answer ✔The intensity of an indicator lamp is
controlled.
Rheostat - correct answer ✔Two-terminal variable resistor
Transistor - correct answer ✔Act like a variable resistor. It's resistance is
controlled by the current supplied to the base.
Amplify - correct answer ✔Increase, the small current presented to the base.
